Axle Lock Bushing for PowerWheels

This is the little bushing the that slides on the axel to lock-in the wheel. I couldn't find a model of it so I just made one and used TPU-GF which has held up great to my sons abuse. It is snug but I would say that's a good thing. PLA Tough works but I also printed a version out of Siraya Tech TPU-GF which worked awesome.
