This wheel assembly is for Kyosho's Car Crusher series, which includes the Double Dare, Hi-Rider Corvette and the Big Boss and is comprised of three components as I have each component labeled:

Car Crusher Wheel V22 - Prototype 3; Inner Wheel Final; and Car Crusher Tire Foam Insert..

All three pieces must be printed, which can then be assemble by using 4 - M3x8mm screws.

Support is required.
