I designed some new keycaps for the PocketType tiny portable keyboard.
The Fusion360 (free for hobbiests) source file is included if you want to tweak them.
There's an STL included, which is the same model as the Fusion source, so you can either load the STL directly into your slicer, or convert it yourself from Fusion. The model is provided upside-down to give the tops the best possible finish, however there's only a single key in the model so you may want to add multiple instances if you want a whole set. Print a couple extra!
They work fine with PrusaSlicer's default settings. The only change I'd recommend is setting the seam to "Back" as improves the quality of the corners and it's pretty easy to hide the seam.
They're tuned for printing at 0.1-0.2mm, mainly because of the internal clips being a little bit resolution-sensitive:
Personally I like to print them on a textured plate with PETG to give them a nice texture.
The internal "shoulder" is designed to bottom out on the top of the switch, which greatly improves the feel - but can be a little hit and miss. If any keys don't sit right on the switches then I'd recommend cleaning out any stringy bits or other 3D printing crud that's in there - the tolerances are fairly tight.
