On the way I am electrifying my old Mercedes Benz bicycle, I have encountered a problem of not easy to remove an out of date Bottom Bracket cap design.
What I did was to create my own 3D printed tool, instead of buying expensive tool just for removing.
Perhaps, this wrench works for other bottom braket caps from Sachs, Campag, Veloce, Thun, than SKF BB cap.

Materials and methods

I used Tough PLA (normal PLA would just works).
No support or adhesion required.

Hi Erik,

Thank you for your comment.

Yes, the bike is just great. Fine parts never fades over decades.

Hi Shigo, you have a Mercedes Benz bicycle? Sounds cool. It looks old, nice that you're extending its life :)

Take care!
