Lotad Dish

TL;DR: I made a two-toned Lotad spill tray upon which the Oddish planters (or really anything) can sit. This model was easy to split into two colors—one for the body and one for the dish. Initially, I manufactured the part using a pause for a filament swap… this turned out ok, but ultimately I decided printing two separate parts gave better results.

Here’s the gallery:

I finished making this Lotad spill tray a few weeks ago, but hella lagged in writing this post >.<;; For those who haven’t kept up with newer Pokemon, Lotad is a Gen 3 water/grass type which has a lily pad on its head. It pretty much looks like what I modeled ;P The dish was made using both the more traditional CAD model workspace to create the lily hat and the sculpt workspace to create the main body in Fusion 360. I created this model with the idea of trying multi-colored prints in mind. The lily pad is to be green and the body is to be blue. I started the prototyping off with a single color print at first to validate the model. After it turned out well, I went ahead and tried changing the filament partway though. The only color I had at the time though was the same bluish-green color I used for my Oddish prints, which was less than ideal. I bought a light blue filament from a new company, 3D Solutech on Amazon. The filament was a great color, and is cheaper than my normal filament, but unfortunately, this material requires a lot more tuning of my print settings (which I have not done yet) to get the same quality of print I can get with my usual filaments. Completing the filament swap during the print was surprisingly easy to do, and the prints turned out quite well. However, the geometry of this model simply requires a huge amount of support for the large overhangs, which seemed wasteful. In my initial design, Lotad’s belly was suspended in the air, so the print required some hard-to-remove supports. To eliminate the need for support material, I made two important decisions. First, I split the print into two parts—the lily pad, and the body. Second, I altered the design of the body so Lotad’s belly would sit more flush on the tabletop. The belly change is hardly even noticeable from a visual standpoint since the entire part is so squat to begin with. Although I need to manually glue the two parts together, the result is much cleaner looking and takes less effort than cleaning the support material.

Shiba Cookie Stamp

TL;DR: I made a shiba cookie cutter/face stamp combo for a friend. As a bonus, I made a bone-shaped stamp with her dog’s name on it as well :D.

First up, here’s a photo of the completed cookie cutter, stamp, and name stamp. The overall dimensions of the stamp are approximately 3in in width and 2.75in in height. 

I received a request from a friend to design and print some stuff for her Shiba’s birthday coming up. I used a photo of her dog’s vest to use as a template I could trace with splines in Fusion 360. In my first version, I made a combined cutter and stamp by extruding various parts of the face to different heights.

While the first prototype worked on polymer clay, it was pretty clear that a few simple tweaks could make it easier to use. First and foremost, it was pretty difficult to press the stamp down since I didn’t include any holes for air to escape. Second, it was a bit difficult to remove everything from the press. Third, since I had fixed heights, the cookies the stamp made would likewise have no flexibility.

Changing to an outline cutter and a stamp for the face addressed all of the issues above and was very simple to do in CAD. The trickiest part was my desire to have a detachable handle to cut down printing time. I created mounting points for the handle by cutting holes beneath the eyes. On the stamp, I made sure to add a larger draft angle on the extruded areas to make it easier to detach from the dough.

I also made a simple name stamp. I was pleasantly surprised at how easy it was to create extruded text in Fusion. The rest of the bone shape and handle were essentially just decorative. I think the name stamp has a potential issue with the letters being too close together, but that should be something easily addressed in a future revision.



Bellossom Print

TL;DR: I created Bellossom model and have sliced it in a few different ways to print. There are two planter versions (one with and one without flowers) and one which is a figurine (no holes). I really like the light green material I have… let me know if you’re interested in buying one ;).

In my Oddish planter post last month (sorry I’ve been busy), I gave a sneak peak of my next project and am finally delivering on it. Bellossom has a much more complex shape than Oddish, and it was fun to use the Sculpting menu along with the Body Boolean Combine menu (cut, join, intersect), move/copy, and patterning tools in Fusion 360.

Seriously, using multiple bodies and the Boolean tools was a real light bulb moment for me. For instance, I needed to create a shell in the head of the model in order to use it as a planter. With the multiple body design paradigm in mind, I used full cylindrical-ish shapes for the centers of Bellossom’s head flowers. Initially, part of the flowers were visible through the wall of the shell, but I used the main head as the cutting tool to slice the flower body into separate pieces—one outside the head and one inside, allowing me to easily remove the undesired inner portion.

Although I created a full model including flower dress, I’ve focused on printing bust versions for now… Honestly, I am dreading the support removal process for the full figure. Practically though, I have the excuse that the shape of the full figure body is not ideal to use as a planter.

Enough boring you guys, here’s the good stuff… the gallery:

Next up, I’m going to be making a Lotad spill tray sized such that Oddishes can sit on them :D. I promise it will take me less than a month to get that line up and running ;).

Oddish Planter!

TL;DR: I created a custom Oddish planter model and printed it. I messed up a few times, but learned from it, which was pretty cool. I’m going to make some other planters too, lemme know if you want one 😉

Here’s a bunch of completed prints outfitted with airplants… I finished some of them with an epoxy sealant to make them super shiny.

Here are the details if you’re interested 😛

The biggest category of goods I’ve always wanted to make on my 3D printer involves Pokemon. I’ve seen a bunch of planters for sale on Etsy and the like, but wanted to try my hand at completing my own designs, so I did. I chose to tackle Oddish first cause it’s a popular with ‘mon with a very simple shape. This ended up being a good learning project because for the very first time on my printer, I needed to troubleshoot print settings and tweak the model to prevent failed prints.

The initial design only took about a half hour to complete, and most of the time was spent trying to finalize the face, feet, and drainage hole designs and positions. I printed the first design with supports thinking it wouldn’t be a big deal, unfortunately, it ended up being a huge pain to remove. For my next iteration, I added a plane cut to the bottom, so the model could sit flat on the table and print without support. While this worked pretty well, I wanted to see if I could improve on the overhang quality.

Then I tried printing the Oddish upside-down. Despite requiring more support material, I liked the fact that all of the areas with overhang would not be visible (except for the tips of the feet). As an additional benefit, I removed the plane cut and give Oddish a nice rounded booty. The first time I tried this though, the support broke resulting in misprinted feet. I tried re-leveling my print bed and adding extra surface adhesive—to no avail.

The breakthrough came when I modified the design, enlarging the feet and changing the angle they sat at such that the support towers started with a larger, more stable base. While I had a successful upside-down print, the support towers left a more visible mark than I envisioned. Additionally, the rounded tush was actually worse than a flat-bottomed one, since Oddish would roll around -_-. The final iteration added the plane cut back in so Oddish would be able to sit flush on the ground.

I’ll be honest–the blue/green filament I bought from Amaz3D on Amazon left me a bit wanting. I’ve had success using their plain black and plain white material before with great success. On initial inspection, the color is spot on what I need for Oddish, so I was pretty excited at the lack of post-print-painting I would need to do. However, after the prints started coming out, there are definitely some noticeable inconsistencies in the filament color, which is a bit disappointing.

The last thing I tried out with these prints was the application of XTC-3D coating to smooth out layer lines and give the parts a shiny finish. The coating is essentially just a 2-part epoxy, which you mix in a 2:1 ratio. The coating ended up being a bit thicker than I anticipated, so I’m glad I decided to wear disposable gloves. The paintbrush I used to apply the epoxy sacrificed its life to give four models a new clear coat. I let the models dry overnight on top of wine bottles, and the result is actually very impressively shiny—you can actually see your reflection in their faces :o.

I posted a little preview photo of the first print (the one with too much support) before my numerous iterations on the model, and managed to get enough interest from a few friends for commissions–yay social media! I’m super happy to say that I made the first sales of my own custom designed planters :D!! I’m excited to take the numerous lessons I learned from this project to continue making new models (Bellossom is up next) for custom planters.

Infinity War Masks

I waited 10 years and 18 movies for Infinity War, and as a superfan with a movie club, I obviously needed to watch it opening night. I bought 22 tickets in the center of the theater within 15 minutes of their availability, but unfortunately, Alamo Drafthouse’s site wasn’t ready when I was. Alamo is by far my favorite movie experience, and the moviegoers there are true fans. It’s pretty normal for opening night premiers to be filled with people dressed up (scroll down far enough and you might see a familiar face :P).

I managed to cajole a few members of my movie club to join in geeking out and dress up for the premiere at AMC. As somewhat expected, we were like the only group dressed up there, but whatever. We had fun and that’s all that matters.

I continue to be pleasantly surprised at the utility of my cheap little 3D printer. This was the first project I completed that involved painting post-print. I found some decent STL’s for Ironman and Black Panther on Thingiverse. While these base STLs worked, there were some changes I wanted to make but didn’t have time to do so, cause of course I procrastinated. I didn’t start making the masks for Abaho and I until 5 days before the movie.

The first part I printed was the faceplate for the Ironman MK50 (Bleeding Edge armor that debuted in Infinity War) helmet. I measured the space between my eyes and scaled everything accordingly. I tried it on and it seemed to fit well, so I continued with the rest of the helmet. It turns out that my head does not have the same proportions as that of the guy who originally designed the model, so I couldn’t get the skullcap on:

At this point, I only had 3 days to print and paint 2 masks, so I decided to cut and print only the front part of the Ironman helmet to save time and ensure wearability. It was pretty easy to make planar cuts of the mesh files using Fusion 360, which was good.

I noticed that the STL I was using was not perfectly symmetric, and the parts didn’t actually fit perfectly together. It’s definitely something I’m going to address before I make my next print.

I needed to do a decent amount of work to prepare the Black Panther mask for printing. First, the raw STL had a ton of unnecessary detail and sharp edges on the inside of the mask, which would have increased the print time and made the helmet more uncomfortable to wear, so I did lot of simplification and smoothing of the inner surfaces. Next, I needed to slice the helmet into a bunch of parts to both fit on my printer, and print in time (I only had about 36 hours cause I ended up printing TWO Ironman masks). Initially, I was worried about having visible weld lines in this mask, but luckily, I bought some BLACK GLUE STICKS a few weeks earlier at Daiso (I didn’t know these were even a thing) to hide them perfectly.

Here’s a gallery of the build process:

Painting the Ironman masks was a huge pain since I needed to cover quite a bit of surface area using three different colors of paint (gold, silver, shiny red). To make the shiny red, I needed to mix a metallic copper paint with the basic red I bought (the red was too flat and bright to match the gold). The Black Panther mask in contrast was ridiculously easy to paint… the mask was already printed in black, so only a few raised areas needed to be highlighted in silver.

I was incredibly happy with how the finished helmets turned out. I added a fabric strap to the back of the Ironman helmet with some hot glue for wearability. It turns out that Abaho’s head fit perfectly within the Black Panther helmet with no additional modifications needed.

Next up, I’m going to be printing out and attaching parts of the Black Panther mask we removed earlier. I’m also going to fix the model symmetry and adjust the dimensions to fit the proportions of my head.

Printer Mods and Cubone Dog Mask

My friends James and Cat found photos of dog owners putting Cubone masks on their doggos like this online, and asked if I could help them make one for Cat’s shiba, Azuki. I searched and found this STL file graciously uploaded to thingiverse to use as a baseline, so I agreed to help.

Here’s the finished product on a very dapper looking, but unhappy dog:

For the uninitiated, here’s the inspiration for the mask:

Since this was my inaugural long print (previous record was about 5 hours) on my 3D printer, I had a number of upgrades I wanted to complete to ensure a smooth print. I found all of these mods on this very useful site.

  • By far the most time saving mod I completed and by I, I mean my roommate did most of the work, was setting up an Octoprint server onto a spare Raspberry Pi I had. This lets me monitor print status from any computer on my network and allows me to send gcode wirelessly rather than need to futz around sending files with physical SD cards.
  • Next, I swapped out the stock cooling fan for a radial blower using the diicooler mod. This mod cools the part from all directions around the hotend, which greatly improves the print finish and dimensional accuracy. I ended up needing to change the wiring on my new fan’s connector. It was a bit of a pain, but I ended up non-destructively disassembling the connector by pushing the pins in and pulling the wires out.
  • After I swapped the cooling fan, I realized that I would need to recalibrate the heating element PID parameters. Unfortunately, the stock firmware did not make this super accessible.
  • In order to calibrate the PID parameters more easily (and add a number of cool new functionality) I changed the firmware running on my printer. I’m currently running the open source ADVi3++ v2.1. Octoprint proved to be incredibly useful here since it let me flash the firmware on the printer from my laptop. Seriously, how cool is that??
  • After installing new firmware, I went and recalibrated the X, Y, Z, and Extruder motors using tools built into ADVi3++ and by printing a calibration cube.

All of the printer setup above took about 2 nights of work. I’m not gonna lie, it ended up being more involved than I originally anticipated. I made the mistake of thinking I obtained all the required hardware, but this ended up not being the case. Oh well, all things considered, it was well worth it.

With all of the printer mods out of the way, I was able to focus on modifying the base STL to fit Azuki better. I asked Cat to take a bunch of photos of Azuki from the profile, top, and front views as best she could. I imported the photos directly into Fusion 360 and used the tape measure she included in the photo (genius move) to scale them exactly. I imported the base file, simplified the mesh, and converted it to a solid for edit-ability. The biggest modification I made other than scaling was the addition of ear cutouts, since Azuki’s head structure was a bit different from that of the base dog’s. I should have added nostril cutouts and could have added additional thru holes for string attachments to hold the mask on more securely, but those can be added after the fact with a regular drill.

The total print time was about 20 hours, using approximately 220g of material. Additional print settings in Cura were as follows: 0.3mm layer height, 30% infill, supports from base only. Cleanup of the supports was pretty simple, I was able to clear almost all of it by hand in less than 2 minutes.

The resulting mask fit Azuki pretty well. The ear holes were in a pretty good location, but the eyes sat a bit closer to his face than ideally desired. The fix for this is pretty simple though, foam padding can be added to the top of his head and along his snout to move the entire mask up a bit. Making the mask sit a bit further from his face will also give his nose a bit more room to breathe as well. From a distance of 2 feet away you can’t see any layer lines or notice any triangular surfaces. I’m incredibly happy with how this print turned out and hope that Azuki won’t hate me too much for making it 🙂

Go watch Pacific Rim 2

Pacific Rim 2 (PR2) is the distilled essence of action movie. I watched it on the opening night in IMAX with 12 friends in my Movie Club. We went in with no expectations at all, and came out pretty pleased. The film delivered exactly what it promised: giant robots, plasma swords, monsters, and John Boyega. It bums me out that PR2 isn’t doing better domestically, cause I’d love it if more films just did what they say they’re going to do. Here’s a totally-not-biased-at-all spoiler-free review 🙂

Freshman director Steven DeKnight delivers exactly what you would want and expect. There’s some set up time at the beginning (admittedly a bit slow), but there’s barely fluff to waste your time with once the action starts. Sure, there’s a jump in plot logic here and there, but who cares–you’re obviously not expecting the Shape of Water here =P.

There’s punchy dialogue and the right amount of silly comedic moments strewn throughout the movie. Mandarin speakers can get a bit more out of the dialogue… Our giant group of mostly Asians laughed much louder than the rest of the theater at certain points. It’s pretty clear the studio is gunning for $$$ in the Chinese market.

Pacific Rim 2 shines with the most important stuff: giant robot vs. monster smackdowns. The action scenes varied in participant design, fighting styles, and environments. I’ll admit the scene selection and framing didn’t seem as painstakingly chosen as they did in the original Pacific Rim (but who beats Guillermo del Toro at that), I found the rehash of assorted elements between each fight kept them all really fresh and visually interesting.

Sometimes you can get away with skipping action movie prequels without missing a beat at all (see: Transformers), but PR2 assumes you’re a bit familiar with the basic rules of their universe. While you could proooobably get away without watching the first movie, if you’re like me and like things to fall into place in your mind, I think you’d enjoy PR2 more with a quick rewatch of PR1. I didn’t really remember any of the repeat characters from the first movie and some of the major plot points which had implications for the second, so I wasted energy trying to rack my brain instead of being fully immersed at times.

Overall, I thought the movie was super fun, and pretty well paced once the action got going. The 1h50min runtime felt just about right, and I’ve got no regrets at all. As long as you aren’t expecting a mindblowing plot, or deep character arcs, I think you’ll have a good time.

Batman Perler Buckle

Four of my friends and I were all bitten by an inspiration bug, causing us to make some light up perler necklaces for those going to music festivals this year (none planned for me though ¯\_(ツ)_/¯). For the uninitiated, perler beads are colorful plastic craft beads which can be melted to make physical pixel art jewelry, magnets, etc. Collectively, we hadn’t seen a whole lot of light up perlers worn out the wild, and the ones we have don’t really look that <a href=” https://www.etsy.com/search?q=light%20up%20perler”> great </a>. So, we thought it’d be fun to make a few for ourselves and our friends.

Personally, I saw this side project as an opportunity for me to tinker with Onshape (a great web-browser based CAD system), make use of my recently acquired awesomely cheap 3D printer (Monoprice Maker Select Plus for $321, all taxes and shipping included!), and practice good soldering (I still need to work on getting better at this, haha).

Despite some flaws, it was a quick (less than a day to make) and did its job of helping us learn and figure out what we can improve on. Instead of using point LEDs, we opted to try an off the shelf <a href=”https://www.adafruit.com/product/1621”> diffuser unit </a>. This gave us a nice uniform background light using a single LED over a relatively large area (45mm x 86mm). Using just one LED in the assembly maximizes battery life and simplifies wire connections. In fact, we only used two other electronic components: a regular coin battery holder and a push button.

The first snag we ran into is the fact that standard-sized perlers are roughly 5mm in diameter, so our lit-up pixel area was actually pretty small (9×17). This greatly limited the designs we could feasibly make. I initially tried portrait-oriented Stanford Tree and Pickle Rick designs, but the low pixel count made it pretty difficult to create anything with intricate details. Instead, I opted for super simple yet recognizable shape: the bat symbol.

After laying out the bat design on the perler board, I created the CAD files in Onshape. Unfortunately, going with a landscape-orientated design was less than optimal, as it forced me to add extra material on one side to make the assembly to keep the lit up area in the center. The extra material made the prototype look more like a belt buckle (or a PlayStation Vita on a string) than a necklace like I originally shot for. The assembly is straightforward though: perlers on top of a diffuser, all mounted in a plastic enclosure with thru holes for connecting to an external battery and necklace string. For this test, I wanted the product to withstand some jumping and bumping yet still be easily dismantled for part reuse.

Inevitably, I procrastinated on this project by waiting to print the enclosure until the morning of the event we wanted to test the product at. Since I had no temporal wiggle room, I needed to make my design bulkier and less spatially efficient to guarantee everything would fit together on the first try. Wire routing posed the greatest assembly risk, so I created troughs much wider and deeper than theoretically needed (roughly 3.5mm wide and 2mm deep). The extra space proved useful and it was pretty easy to put everything together.

Here’s a list of observations that were made, immediate improvements, and things we can try for the next version:

  • More melting of the perler beads, to ensure no light bleeds through the center of individual beads. Having holes still visible meant the white backlight bled straight through and washed out the design completely at most angles.
  • If melting the perler beads more doesn’t work, we can add a resistor to reduce the harshness of the backlight.
  • Add a mask directly on top of the parts we don’t want backlit
  • Take time to actually plan wire routing, use smaller wires and thinner troughs to minimize assembly thickness
  • Replace screws with the aforementioned snap feature. This will also help thin out the assembly.
  • Optimize the placement of the battery and on/off switch.
  • Either reduce the size, or replace necklace form factor with belt attachments.

Codebreaker (Game on Google Sheets)

I discovered the game Codenames a few weeks ago through my friend Sabrina. It’s a really simple and fun word association game that has kinda caught fire among a few of my disparate friend groups here in SF. It’s a great party game for 6 or more people, that I’ve found myself playing quite a bit recently. I figured it would be nice to build an online version so we don’t have to worry about bringing the box everywhere, spills on the cards, etc.

Each team chooses a captain who will be giving clues to their teammates. A 5×5 grid of random words is created, for example:


A hidden key pattern is also created, but is shown only to the captains:


In the version I made, red and blue are the colors for the teams, gray is neutral, and orange is the instant-loss square.

The goal of the game is for the captains to give one-word associative clues to help their team identify their team’s words on the board (while trying to avoid words of all other colors) along with a number of words to be guessed. For example, if it is the red team’s turn, the captain could say “Princess for 2” in an attempt to get their team to pick Barbie and Daisy.

Their team then discusses for a reasonable amount of time and starts picking squares to check. During the discussion, the captain should not give any visual hints or reactions, but he or she should definitely be listening to where their team’s groupthink is headed. If the team reveals a square that isn’t one for their team, their turn ends immediately. Each team can pass at any time during their turn, and can guess one word more than the number their captain says (in case they passed earlier). There’re also other minor rules like restricting rhymes, proper nouns, parts of speech, etc. but I prefer to leave these as house rules.

If anything isn’t clear on the gameplay, this video is a bit long (10 min) but seems to do a decent job explaining:


Anyway, I buried the lead a bit I guess, but here’s the link to my sheet… feel free to make a copy to play (File -> Make a copy). The idea is that you connect a computer to a projector or TV, and the captains access the captain board on their phones, or a separate computer.


Everything is controlled through the “Codebreaker” menu. “Generate new board” reshuffles the words in the wordlist tab, “Generate captain board” creates a new hidden pattern, “Check selected cell” reveals the hidden color for the selected cell, and “Clear board” clears the colors from the board.

Codebreaker Menu

I used Google Sheets because everybody has access, and I’ve wanted to play around with Google Apps Script for a while. It’s actually pretty well documented, and examples were easy to find. The project overall was pretty simple and only took a few hours for me to complete, most of which was spent inefficiently, typing out 500 words into the word bank while watching movies.


EDIT: Speaking of words though, I’ve had a few friends ask me how to add/edit the word library… It’s pretty simple, just be sure to make your own copy of the spreadsheet, or anybody accessing the original will be able to mess up your game.


To edit the wordlist, just go to the wordlist tab and add words into column A. Just be sure to drag the formula from column B down to cover any words you add, just like in excel. Alternatively you can just type the function “=rand()” into column B next to any words you add. In this example, I’ve added the word Slipper, and to complete the addition process, I can just drag the bottom right corner of B500 into B501.


I don’t plan on really maintaining or further developing this because it’s pretty functional for what my friends and I need, but there’s just a couple of things I’ll try to complete sometime:

    – Randomize red/blue team starts. Right now, the red team always goes first (and has an extra word to guess)
    – Keep track of points scored by each team
    – Make a better UI experience via having control buttons on the sheet.
    – I would like to create a better way to get the link to the captains’ phones, and maybe make it easier to not accidentally show the captain board, maybe via a password protect.
    – I could also include the instructions for how to use the sheet, but ehh I think it’s pretty self-explanatory.

Have fun!

Political Speculation for Funsies

Even though it’s already been 2.5 weeks since Cruz and Kasich dropped out (it feels much longer though, doesn’t it??), I’m still in a state of disbelief that Trump actually won the GOP presidential nomination. For me personally, this situation illuminates how much of a bubble I still live in, despite my efforts to look outside of it and understand different perspectives. Clearly there’s still a lot of pain out there driving so many voters into the arms of such an authoritarian candidate who built his platform by playing on fears.

Denial is the first stage of grief, so I figured it would be fun to come up with some House of Cards-esque (admittedly far-fetched) scenarios which would prevent both Trump and Clinton from getting into the White House. Keep in mind that this is fun speculation, a ton of wishful thinking on my part, which evolved into a joke that has actually been kinda therapeutic for me.
