Patron 920 Crank Lock

With eBikes turning the crank backwards does not move the chain due to the way the drive functions. This makes lubricating the chain difficult unless you have a bike stand. This piece allows you to temporarily link the crank and the gear together and then rotate the crank backwards, moving the chain. This fits the Scott Patron 920 but may also fit other Scott bikes.

To use it rotate the crank so that the longer protrusion can locate into a slot on the gear then hook the other hooked protrusion around the crank. The pictures hopefully are self explanatory!

I printed with 75% infill and standard PLA and it seems plenty strong enough.
