shimano TL-FC38 alternative

thingiverse

This tool helps you to remove the chainring of your shimano steps ebike. You'll need a 32mm spanner/socket wrench to turn the tool. NB it's a left-hand thread, so turn right to loosen! This remix from pvdm's version adds a smaller hole. You can use the pedal bolt to keep the tool in place when you apply force. That made all the difference for me, because without it the tool would twist away and strip it's teeth. I made mine from PLA and that worked.
