This is just a simple Minecraft Skeleton face keycap.

It should fit on Cherry MX or other similar mechanical keyboard switches.

I used an AMS to print the cap in white and use black and grey for the face.

You could just use black or grey for the face and do a pause/filament swap (layer 65 in my 3MF or about 10.12mm).

Manual supports added for switch interface only. 3MF is set for a .16 layer height. with ironing on all top layers and .36 top line width.
