I needed an easy way to remove a bearing from a bottom bracket. This is currently modeled for an Enduro T47 External Bottom Bracket with SRAM DUB (29mm) spindle. This was super basic to do via tinkercad. If you need a different sizing or spec, I am sure it would be easy to redesign with minimal issues. Images attached for use case.
The larger tool is to set the BB into and has a lip to allow the bearing to push through.
One side of the “punch” tool is sized to fit in the BB shell and the other side is made to be the same OD as the bearing to be used as a setting tool.
