This is a tool to install an octalink 8 notch bottom bracket.
Since it's plastic and small notches. You probably won't be able to get a stuck one off or put enough torque on it before breaking.
But this will allow you to but one on without scratching the bottom bracket trying to use other tools. If you (like I did) use this to put on a bottom bracket I would recommend getting it properly torqued at some point.
I've included two STLs. The "8 notch bb tool.stl" has slightly wider notches than the "- smaller notches" file. I have to press it into the bottom bracket for it to fit.... so it's tight. If your printer tends to print big, or you don't think you have good tolerances, I'd recommend the smaller one. The bigger the notches the harder it is to break it.
