FingerBoard Skateboard Wheels Resin Print Only

My son has a fingerboard and one of the wheels split. So I designed and printed new wheels. Not sure if all the bearings are the same size. This seems to have a 4mm bearing. I made the wheels a little bigger at 7.5mm. Yes there is a name and size on the wheel. My son.

This is the board it fits: Peoples Republic 32mm Purple Complete Wooden Fingerboard w Nuts Trucks - Basic Bearing Wheels from Amazon

You will have to have a DLP, SLA, LCD to get the print this small.
