608 Bearing Puller Tool for Skate Wheel

thingiverse

This tool extracts bearings from skateboard wheels, specifically 608 bearings. It was designed and printed by me, with initial success but also a breakage after the first use. I'm confident that others can enhance or modify this design to make improvements or offer suggestions. Update: I made some adjustments and reprinted it, using it again without any issues. The key to its effectiveness lies in inserting one side through the bearing at a time, rather than both sides simultaneously. This modification improved its performance significantly. I printed the tool with regular PLA filament. However, other types of filament may work better for this application since flexibility is crucial for extracting bearings successfully.
