You should know about styrene. It is a really easy material to work with because two pieces melt together really easily and fast with a solvent glue like ”Weld-On 3″. It’s the same Weld-On for acrylic, but it works even faster on styrene. For example, I’ve made this prop (see below) in about four hours. On movie sets, most of the props are nothing but styrene. You can paint it to look like anything. And styrene is sold in about a bazillion form factors — rods, tubes, sheets, textures.
