I added the icons in OrcaSlicer and because of this I can only export this as a 3MF file that is compatible with Bambu Studio/OrcaSlicer. I'm sorry :(
---------------------
I uploaded profiles for a single blank keycap and all icon keycaps together for a 0.4mm nozzle and a 0.2mm nozzle.
I highly recommend printing this with a 0.2mm nozzle!
I did print a few of these keycaps with a 0.4mm nozzle for test purposes and they did work (you can see these in the third picture) but I can't guarantee that every design will print well (for example the D20 most likely wouldn't work).
In the slicer the icons only show after slicing and not in the preview. But every keycap should have a name in the object tab.
Easiest way tro add your own icons (with OrcaSlicer):
These are the SVG settings I used for the keycaps as a reference.
Most Icons are from here: https://www.discotools.xyz/de/icons-editor
And this is the 3D printed Macropad in the picture: https://scottokeebs.com/blogs/macropads/scottodeck-handwired-macropad
The author remixed this model.
I used the xda keycap from the original link as a base. Had a problem with the fit and added a negative part to make the cutout for the stem a little bit bigger.
