This is a model that I got from Angel Falcon on GrabCad. I made some modifications, and scaled it to 1/3 scale for a project I am working on. The parts were tumbled in a cermaic tumbler, hand sanded and finished to a mirror gloss black, and a matte for the inner spokes. The rim and spokes were printed using SLS technology. The center-cap was printed on a DLP printer for better resolution and fine detail.
