Replacement Wheel Assembly

Wife said the microwave was smoking! The microwave was built in '84 and would hate to see it go because of a simple wheel was arching to the case. I gave the project of making another one to my son so that the micro would be functional again. He did a great job! It works even though the wheel doesn't spin. We will take the work in progress off when we have figured it out.
Printed it right side up.
