Summary

The P26 part changed between V2 and V2.1 and for whatever reason I needed the new part. This is a printable version of the new part (won't fit a V2 although you could easily fix up the scad file to fit). You need 4 total.

Printed with 1 perimeter. Had to just kiss the mating pieces with a file to make them go in easily. This may be better than original because the plastic "snaps" onto the 8mm rod!
