My son's Tamiya Lunchbox front rim broke; unfortunetly, we were going on a trip in a few days so didn't have time for new rims to arrive. I modeled the rims and printed in a few hours. The rear rim eliminates the separate drive hub so the front and rear rims look the same when bolted on.

The rims were modeled to look like Cragar SS rims by the way.

I drilled the rear rims with 13/64 inch bit (5.1mm) after printing to help slide the rear wheels onto the axle.

I've included some test hubs so you can dial in print settings more easily.
