[sdiy] Molding your own keycaps for tactile switches?

[Chad Coffman]

This guy created his own 303/606 knob replicas. I asked him where he got them he said, "The knobs are a epoxy cast to match the original."

  Has anyone tried this?  I recently stocked up on a variety of tactiles on ebay, assuming that the caps wouldn't be too hard to find... Much to my surprise these seem quite rare, and certainly lacking in variety.  Mostly black circles and squares, ho-hum.   I remember reading about how some people were molding plastics to make their own knobs and such (on another forum, I believe) and the designs I want and pretty simple in terms of shaps, no embedded LED's for the most part.  Has anyone worked with this kinda thing?  What I'd really like is a soft-touch rubber material in several colors...  But I'm clueless where to start.  Elastomers?
