12-notch Tool for bbinfinite T47a bottom bracket
thingiverse
Replacement for the installation tool BBinfinite ships with their T47a bottom brackets (T47 asymmetrical a.k.a. BBRight or BBcorrect). The 12-notch tool sits on the non-drive side and is clamped onto the BB shell with a threaded rod and the plate on the drive side. This prevents the tool from slipping off. Torque can then be applied to the NDS through a socket wrench size 32. I designed this because my (original) installation tool slipped off and I stripped some of the nylon teeth. Also, the 16-notch interface of the tool wouldn't let me use my torque wrench and I couldn't justify the investment for an adapter I'd only need once. Tool dimensions:<ul><li>oD = 50,0mm</li><li>iD = 47,7mm</li><li>12 notches</li></ul> I've attached the .stp-file for you to modify, in case you need different wrench sizes.
