Summary

To reduce rubbing with larger tires, i made new lower links out of TPU that i could then bend out of the way (was doing the same with the stock links but i was worried they might snap)

Also included an STL for a stock link that will accept the metal pivot balls, they would likely break with PLA though, and TPU they were far too flexy.

The flexy link model was perfect at 30% infill with TPU
