Broke the original by accident and the part is discontinued. Designed a beefed-up version that can be 3d printed. This design uses the original bearings. If the bearings fit too tightly, gently heat the part and press the bearings in. This will give the bearings a better fit and prevent excessive stress.

This part has been tested in PETG and PLA. PLA is too weak and will function fine until impact. If the wheel clips a edge and pulls, it will snap the PLA. Once printed in PETG, I never had a problem.
