This is a tool for installing or removing Shimano Hollowtech bottom brackets.
This should fit XTR BB93,  Dura-Ace BB9000, maybe a few others. I think there are 2 types of hollowtech bottom-brackets and this fits the slightly smaller ones.


if your bottom bracket is seized in the frame this tool may not be adequate, it is only plastic after all.


This is a very tight fit, if your filament shrinks when cooled you may need to scale the model slightly.

I've included a small test print (just a few layers) so you can make sure this tool fits before wasting a lot of time and filament.
