Another member of 8thalga and I are making replacement analog stick covers for our PSP's. (Mine broke, and he just wants to replace his) I'm posting here to ask for a few suggestions: What material do you think we should use? It's just the cover itself - so it's the top and the bottom. There aren't any wires or anything involved, so keep that in mind when suggesting. He has a glass chess set, and we were thinking of using the bottoms of some of the pieces to make them. Another idea of mine was to use a hard rubber base, but it'd be pretty hard to find. We can't use anything that'll crumble, so clay is out, unless it's hardened. What do you guys think?
