Knitting lends itself to computation very well. Here is an example of a leaf 'algorithm'. Definitions are listed at the top followed by a loop. Complexity is built on fundamentals, shown in this owl pillow. Jake shared this paper on fully 'computational-ized' Automatic Machine Knitting of 3D Meshes. My initial hypothesis is that the complicated manner current knitting machines comes from replacing a stick with hundreds of hooks.

An amazing analog 3D printer by Daniel Debruin .Here is 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. How can something like this be implemented in a NC knitting machine with passive adaptive mechanisms?
After falling into a youtube rabbit hole, I did find out an analog knitting machine does exhist! 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.
