The Supermobile is 3D printed in PLA plastic (red, blue and silver) with some vinyl and acrylic details. It takes over 35 hours of printer time to make all the pieces for one.
The design is a cross between the Corgi version (arms and fists) and the Superpowers version (bumpy seat and boxy design). The arms are articulated and the fists are spring loaded and can shoot, like Baron Karza.
The box was designed and produced by The Toyroom based on the cover of Action Comics #481. Thanks Anthony -- you knock it out of the park!
