This is a BB tool designed for 41-42mm OD bottom brackets with 16 notches, notably the Shimano SM-BBR60 and 1/2in square drive socket. Suprisingly, even when made out of plastic, this thing works, and tightened several bottom brackets to specification torque without any issues.
Tested with carbon-filled PETG at 100% infill.
