Use case: I use a regular (not narrow-wide) chainring in the middle position of a triple crankset; a poor man's 1x drivetrain. I currently use a front derailleur as a measure of chain retention, but I still get rubbing when in either…

Broke mine, so I designed a new one. Print with whatever you like, any material will be fine, any 0.4-0.8 nozzle does the job. Designed in Fusion 360. Made 2 versions, both are fine, v2 stronger on the edge. Have fun!

This tool was inspired by this Park Tool video . I thought it was a great idea, & decided to create a handle to make it significantly easier to use. I don't believe this works for cassettes - the tooth profile is more "square" instead of…
The joint is based on a balance between friction and tolerances; although the design also takes this into account, it may be advisable to test the relationship between print speed and extrusion speed. Obviously all the other parameters…

This is a pretty specific print that very few people are likely to need. But just in case, I figured I'd upload it if anyone else needs it! This is a socket for the chainring locknut on some E*Thirteen cranks. Not 100% sure which exact…
