I developed this tool for removing the bearings of a Raceface BSA 30 threaded bottom bracket.
There is only 1 mm of the inner race of the bearing available to push it out, so I opted to remove the cups out of the frame so that I can use the full circumference to press the bearing out of the cup.
The sleeve uses the notches in the bearing cups to position it properly.
I used the Wheels Mfg rod (12 mm) and handle, but any threaded rod (12, 10 or 8 mm) with nuts and washers can be used.
I used PLA for all the parts.
To ensure they are strong enough, I set the perimeters of the vertical shells at 12, the solid layers of the horizontal shells at 8 and the infill at 60%, cubic, so the parts are almost solid.
A metal washer can be used between sleeve and handle if necessary.
