I wanted to make my board cooler but it's almost impossible to find keycaps that fit my switches so I decided to make one that can fit any keyboard. I found a nuke coaster from HEAVYLIGHTS over on thingiverse and decided it would be perfect for this project. I scaled it and cut out a space for the keycap to go, it only needs basic supports on the bed for me but if yours works better with other settings comment what you used and I'll update this. To install it I used some hot glue on the bottom then I just put it on the keycap and it works perfectly and don't worry about your keys being ruined if you take it off as long as you use hot glue then it should be ok.
