Notes
Friends told me it wouldn't work and that the plastic would fail. They were 100% wrong. This thing exceeded my expectations. It is very very solid. My bearings were glued in with RED Loctite 263, this puller made mincemeat of the Loctite and the bearings pulled out first time giving little resistance.
I printed with 5 walls, 100% infill and in Flashforge black PLA. If you prefer the professional look then print it in Park Tool blue
