If anyone is interested, there is a discussion going on currently on the cameramakers discussion group about making plastic cameras. Lots of advice about different methods of molding different plastics. This discussion group began as the society of handmade cameras, which seems mostly defunct. Somehow, I don't seem to have the address even though I get the messages. I found this in a search http://rmp.oposis.com/mailman/listinfo/cameramakers.
