Socket wrench for Wheels Manufacturing PF30-THD threaded bottom bracket

Posting this despite not getting very good photos of it.\n\nIf your carbon fiber bike frame has a PF30 press fit bottom bracket, there's a good chance the fit will loosen over time and you'll need to replace it. In many cases, Loctite 609 or 680 can fill the gap, but often the best solution is to switch to a thread-together bottom bracket like the Wheels Manufacturing PF30-THD-BB, which holds itself in place by threading together inside the smooth shell.\n\nThe only real issue with this solution is that you'll need a special wrench due to its larger outer diameter. Wheels Mfg makes a socket and a wrench, but the design is simple enough that 3D printing can create one.\n\nMy design for a socket uses a 1/2" drive, which can handle more torque than a 3/8" drive since we're dealing with plastic. The socket also sinks into the bottom bracket so that turning force is directed almost inline with the interface - longer sockets are tough to use as they tend to rotate off and turn the bottom bracket. I include a wrench because you'll need it to hold the opposite side.
