Bottom Bracket Tool 48.5 16 notch (wheels mfg + others)

This is a tool for the 48.5mm threaded, external cup bottom bracket with 16 notches. It will fit a standard ½ inch drive and can be used on a torque wrench. 

Print with the strongest material you have with at least 5 perimeter, possibly even solid. I've used ASA and I'm impressed with how tough it is. It is never going to be as good as a metal tool, but even if its only single use it will save you have to spend £45 or so on a specialist tool.
