[sdiy] Molding your own keycaps for tactile switches?

[Graham Gleich]

My Uncle is a Chemist for GE that works specifically with plastics. 
He has worked over the years to develop a number of products such as 
a replacement plastic for LEGO (tm) that has a smaller waste factor, 
due to a reduced number of discarded molecules being produced in the 
manufacturing process... He might have some suggestions  for 
materials that is easy to work with that would also have a fair life time.
