Friend got a 3D printer, could we make keycaps?

[Xarmydis]

My friend has wanted a 3D printer forever, he finally got one, and we both enjoy our keyboards. It just hit us that people make custom keycaps with 3D printers, but we don't know if we could/how to go about it! I couldn't immediately stumble upon anything, are tehre any resources out there I should look for?

If this is any help, here is the printer:

Extrusion printers really aren't recommended for something like that.  They tend to get pretty crappy results since they don't have the fidelity you really need.

You can do it, but I agree that FFF/FDM printers are not good for it.

If using ABS material you can maybe smooth out the 'threaded' look by applying a little acetone (which dissolves ABS) to the surface to melt it smooth. I haven't tried it because I haven't got any acetone on me, but I'm curious to try it now.
