Key cap (Nắp phím)

I have a K95 Corsair RGB keyboard and I couldn't find any good key caps that supported my RGB and had the symbols I would want for game streaming, so I designed my own. 

If I don't have the key cap you want, use prusa slicer on the blank key cap with a negative volume to imprint whatever symbol you want.

So the outer piece can be printed in whatever colour you want, and then the inner piece you print in a clear Or translucent filament
