Keycap models #
Keycaps are hard to source at the time of writing. Some people use caps for Kailh PG1316S switches, but I couldn't find a store that had them in stock.
Luckily, other people have already modeled 3D-printable caps, see pashutk/Cherry_MX_ULP and the linked projects.
I liked the version by marcoster and jonboh/ulp-dactyl and added three modifications:
- Rounded corners with 2 mm radius,
- spherical[1] top surface curvature and
- homing variant with bar at the bottom edge.
Here is the onshape document. The caps are laid out as sheets for cost-effective on-demand printing; 64 blanks and 9 homing variants.
The step files in this folder only have one cap.
Tips for FDM printing #
You can print these with an FDM printer. I used a 0.2 mm nozzle, adaptive layer height and Arachne wall generator and printed the caps face up and with automatic support. I found traditional support easier to remove than organic support.
