[sdiy] Molding your own keycaps for tactile switches?

[Heitor Alves]

Hi Jeff & gang
 i've once buy several of tact switches for a good price. i couldnt find any 
caps for it, but i've used old keys from a keyboard, i glued then togheter 
with super glue(?). they looked nice. heres a pic of them: 
http://ignatz.alojamentos7.com/p3seq002.jpg about molding, i havent any 
experience in molding plastic, but i've found a easy stuff for molding... 
its called polymorph, you heat it in hot (60ºC) water, let it melt then 
rinse and mold, you can use a hot air gun to soften because it gets harder 
has it gets cold.
 regards!
