I developed this tool for removing the bearings of a Wheels Mfg BBRight bottom bracket for Shimano (24mm axle).
The sleeve uses the notches in the bearing cups to position it properly. Only a sleeve for the cup tool size 48.5mm/16-notch is included.
The sleeve is designed to apply no direct force on the frame, but only on the bearing cups.
The adapter should be fitted behind the bearing. If both bearings are still fitted, this is a bit of a fumble. I use a tiewrap to hold the apdapter in position behind the bearing and then push the rod through the adapter and bearing. Should the adapter fall into the bb housing, it is easy to pick it out.
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.
