Old original Mendel z-driven-pulley_2off part (no rim)

Every once in a while I want to print out the ORIGINAL version of the z-driven-pulley for the Mendel (before someone added a rim). It's not easy to find online anymore, and I want access to it from anywhere, so it's going up on thingiverse.

I mainly print these now to put on badge holder lanyards. :)
