I'll try and get to the bottom of it. I know some people who know some people

i just think it would rock for the SD2SNES which has 3 colored lights on the board. and yeah i was talking about casting, just thought it would be worth it to ask.
It can most definitely be done, but it wouldn't be easy. Puling air-free, perfect parts from a mold which is not poured under vacuum is quite tricky. What this means is that you'll need to spot fill pits and air pockets, which of course ruins the whole clear shell thing

I've got a make-shift vacuum casting setup, but it's far from industrial grade, and I can't get 100% perfect parts from it (more like 90-95%).
