TL;DR: I designed and printed a booklet maker for a friend.
Instead of completing the Inktober challenge I spent the month of October designing and printing gifts for friends… and I spent November writing about them, haha. I posted about a Darth Vader dice tower here, an Ironman figurine here, and the third project I completed is this booklet maker.
My friend Will reached out for help solving a specific problem: he likes to
staple papers into booklets, but needed a way to make them more easily and
consistently. We went back and forth with some requirements (number of sheets
at a time, staple placement, etc.), he drop shipped a stapler to me, and I
I began by modeling the classic Swingline 747 stapler from caliper measurements.
I needed an accurate stapler model to ensure a good fit for whatever 3D printed
part I would ultimately design. Capturing the draft of the side and determining
the clearance available during stapler actuation was of paramount importance,
so I created the stapler in two components and added movable mates.
For this project there were advantages to taking a top-down design approach. In a new part model, I created a layout sketch to place the staplers per the desired specifications 6 inches apart on a line ¼ inch away from the left margin.
With the staplers fixed in place, I focused my attention on the design of
the main paper retention body. The trickiest part of the design was creating an
attachment method that keeps a clear path for the stapler head to reach the
After completing a test print to check the fit, I made a few adjustments to
the paper backstop height, mirrored the body and connected the two halves with
beam extrusions. Pictures speak louder than words, so here’s the build gallery:
Will tells me he’s very happy with the results, and I couldn’t be happier
TL;DR: I made a villainous dice tower for a friend’s bday, combining two of
his favorite things—Star Wars and board gaming.
October was a pretty busy month for me with work and fantasy football both
ramping up. However, I’m very happy I was able to get some design and project
time in. My friend Nick’s birthday was earlier this week, and I wanted to make
him something practical yet personalized. Anybody who knows him at all knows
how much he loves both board games and Star Wars, so to me, printing a Darth
Vader dice tower was simply a no brainer.
For those of you who may not know, a dice tower is a very simple device to ensure
fair rolls while keeping dice from flying all over the place and messing up
stuff on the table. Dice towers can take on a wide variety of shapes and sizes.
All that is really needed is some sort of aperture at the top to put dice in, a
path which randomizes spins, and a tray to collect them at the end.
Before I started designing, I did a quick search on thingiverse and other 3d
print sharing sites to make sure I wasn’t completely reinventing the wheel. I
found a few Vader dice towers, but to be honest, I didn’t think they were very
good in terms of amount of detail and general aesthetics. I was fortunate to find
a great model of Darth Vader to begin with: https://www.myminifactory.com/object/3d-print-star-wars-darth-vader-30-cm-tall-60500.
Essentially my plan was as follows:
Reorient and resize the head to maximize the print area
on my bed.
Create the dice travel path leading from the top of the
head out of the mouth.
Subtract the path model from the head model.
Create a tray to catch the dice
Print the parts
Parts 1-4 went incredibly smoothly all within Fusion 360. I successfully
printed a ¼ size test part to ensure the path I created could be printed
without any internal support structures to minimize post processing work.
Unfortunately, I then ran into printer issues I had never previously
My Monoprice Maker Select Plus (aka Wanhao Duplicator III Plus clone) has
been a workhorse without any major issues for years now. Of course, she decided
to act up when I was up against a deadline since birth dates are immutable. My
printer would randomly stop working and send bed temperature errors before
rebooting. I pinpointed the problem to the thermistor on my print bed, but I
didn’t have time to mess around. Luckily for me, my neighbor across the street
literally has a print farm in his bedroom (15 machines and counting) so I was
still able to get the parts made on time. The only unfortunate thing is that
his machines are smaller than mine—so he had to scale the size down by 5% to
get them to fit. (I found out later that the fix I needed on my printer was
incredibly basic: the kapton tape holding the thermistor to the bed loosened
over time, thus the printer received intermittent temperature readings.)
Luckily, the 5% reduction in size did not severely diminish the part’s
I’m incredibly happy with the results of this project. I enjoyed the challenge of modifying an existing mesh to create a new, meaningful, and practical object. Even though UPS spoiled the surprise by giving Nick a notification about the arrival of a package sent from my area, and the package arrived late, I’m pretty sure he was very pleased upon arrival.
Thanks for making it to the end of this post—here’s an incredibly sparse
TL;DR: I made a divider for our new laundry bin using material from our old
bin and printing some threaded pins to hold it in place.
We used to have a stiff cloth laundry basket, but there were two main
problems with it. Whenever I tossed my clothes on it inaccurately (this
happened all the time, let’s be real), the walls would buckle a bit under the
weight. Secondly, there’s just a single compartment, and I’m allergic to the
laundry detergent Tiff likes to use.
To fix the first problem, we actually used the ubiquitous 20% off Bed Bath
and Beyond and bought a new hard plastic hamper. To address the second, I got a
bit more creative. Since our old laundry basket was cloth-based, I was able to
fold it up using binder clips. The divider fit very tightly near the bottom, so
I only needed a way to hold it in place closer to the top. I created a pocket
on each side by adding two binder clips around where I wanted to place the
The custom design I went with was very simple—it’s a simple threaded pin and
retaining nut. I measured the hole I needed to fill, extruded a few cylinders,
and added threads, ezpz. About two hours on the printer later, I installed two
pins with nuts on the basket and put the divider into place.
I’ll be the first to admit that this isn’t my sexiest design ever, but it’s
