A Laser Cut, Modular Utopian version of Jake's Roller Coaster Tycoon Axis...in the works. Still need to do more kerf adjustments and incorporate snap fit details.

To start off, here is a machine that I like very very much by Daniel Debruin. Below - a closer look at the 'guiding mechanism', a hand bent rod that acts as moves the print plate creating the profile of the clay vase.

After falling into a youtube rabbit hole, I found another machine i like very very much. Behold - a Vintage Sock Knitting Machine. Around 14 minutes is where she begins the heel. Here are some photos of one of these machines from Old Tymes Stockings.
D E T A I L I N G [snap-fits]
Currently I am most interested in this snap fit detailing. After helping Rob with a rebuild of Jake's CNC, I understand the allure of snap fits. To get started, here are some downloadable snap fit files from Stanford's Transformative Learning Technologies Lab.
On a tangent but related note, here are Japanese wood joinery GIFs from my favorite twitter account.
I am going to be ambitious and aim for a reversible snap fit with some compliant mechanism. Here is the first pass:
Laser cut tests below. While they did snap they did not make a good fit.
I didn't think it was going to work, the arcylic was not nearly elastic enough. But I tried it anyways and then found a really helpful paper on Use of Snap-Fit Fasteners in the Multi-Life-Cycle Design of Products . More to come -

Week of 3/19 - As part of a class goal, I took on Jake's suggestion to attempt some rack and pinion teeth in Antimony. Below - a screen shot from the history of Jen's Fushion 360. [It looks like an approximate spline of part of a cycloid]. Then - the Antimony attempt. I tried to just use the cirle and rectangle components. It's not mathmatically correct - and probably needs to have a proper cycloid scripted?

Machine Project Thoughts - I'm approaching the Global Humanitarian Lab challenge for a modular fabrication lab with some optimistic scepticism. I would like to integrate a hand crank onto the motors so they can be used as simple hand tools like a drill press if needed. This is based on this mill in our machine shop that has both CNC and hand crank options.
The crank is mounted directly onto the motor [so it's also really fun to watch when running because the motors move the cranks too and it looks like a ghost is making some parts].
Below - Quick sketch of a one axis mod with a manual component [these will be heavily based off of Nadia's reconfigurable stages but stepping up from cardboard to plastic or aluminum]
Updated sketch - In addition to swithcing to a brushless motor for positioning, I'm imagining a second fixed mount opposite the motor.
