Grey nylon plastic with a subtle metallic sparkle (formerly Alumide.)
About this Product
Heart Rocker Base for use with seat. Used on Challenger and Big Boy. 1/8th scale. Some machining is required depending on what you want to do with them. I have no idea how well the materials provided by Shapeway will machine. I am providing this as a DYI and purchase at your own risk. This is the base model I used to CNC mine out of a solid.
