The original version of these caps was created by Pseudoku, proprietor of Asymplex. The original repository is still available here and there is a wonderful writeup by the creator at KBD News.
The versions in this repo are modified to include the rather odd internal cutouts for mounting on PG1316 (and PG1316S) switches. There are 4 such cutouts available, each of which has a parameter in the files:
- pg1316_old: the official cutout shape, as seen in the keycaps Kailh sells. Works great with the switches, but hard to print accurately.
- pg1316_nofoam: an improved, "EZ-Print" cutout designed by Mike Holscher to be easier to 3D print.
- pg1316_foam05: the EZ-Print cutout, but 0.5mm deeper. This allows space for a very thin layer of foam for sound reduction. As a result keycaps need to be 0.5mm taller.
- pg1316_foam1: EZ-Print cutout, 1mm deeper, providing for a thicker foam layer but requiring yet more keycap height.
There are a couple other odds and ends (my personal choc DES for example) which you can use at your own risk, but understand I am not keeping them in any particular useable order.
Clone the repo and use OpenSCAD to open the keycap file (one of the .scad files not in the libraries dir), then edit the parameters near the top to generate a keycap. Export to .stl or whatever else.
Shouldn't this just be a fork? Pseudoku's repo has been forked numerous times and has a long history. I forked zzeneg's fork in order to adapt some of the profiles to the new Kailh PG1316S switch; I quickly discovered the repo is impractically large, and a good portion of that is because the .git directory has grown to over 1.5GB. Most of the rest was .stl exports.
So I created a new repo with only the files necessary to create the keycaps. Any STLs I make available will be elsewhere (and I will put a link here). So far so good: this repo comes in under 1MB vs >3GB for a "real" fork.

High sculpt smooth transition profile
Subtly sculpted choc spaced low profile
Additional sculpt angle and smoother transitions
