Title: Need Help Designing Keycap
Post by: Firebolt1914 on Sun, 11 January 2015, 10:24:11
Hey guys, I currently have an idea that I want to make a reality, and I have no clue where to start. I've had the idea of glass keycaps, which have been thought of before, but usually never done. What I found to be the main failing point is the stem, which I've made a solution for: having a hole in the keycap for a plastic stem. The only problem is, I have no idea how I'm going to make a mold for that. If anyone has any pointers or tips, please post them here; I would really love to be able to make glass keycaps.

You're going to mould your own glass, or what?

I'm most likely going to cast glass, and I need a mold for that. The problem with that is, is that the stem is really fragile if made out of glass.

Therefore I will need to have a hole where the stem usually is, and put a plastic stem there.

I have no clue how I'm going to make a mold for a keycap with a hole instead of a stem.

There was a thread about this earlier but the guy never made the caps afaik. I'm so excited to see these if you follow through. Good luck!

Buy small little squares of glass and use hand glass cutting tools?

Neat.

Sounds like you need 2 molds: 1 for the glass "cap" and 1 for the plastic stem insert.

Also, it seems rubber o-rings might be highly suggested for use with glass key caps.  Nobody wants to shatter his key caps (and fingers!) from bottoming out too hard on a keystroke.   :p

I would say make the stems in a way that they snap into the glass part, and that they cant be rotated at all. Those are the first issues I see. Also, make sure the stems are not too long or short. Perhaps make the plastic stem and a base insert for the bottom as well, so when the key is bottomed out, it wont be glass on plastic, I dont think that would sound too pleasant. Or, you could use permanent o-rings, and make the stem a little longer?

I dont know what you wanted out of this thread, so I am giving you as much advice as I can :D
