Spool Holder for Mendelmax 1.5

Inspired by other similar designs here on Thingiverse.

The rollers are made from 7/8" Aluminum round stock drilled and tapped 5/16"nc on both ends.

Use small washers to keep the knobs from tightening against the bearing race.

Cut the 5/16" bolts such that they bottom out in the tapped holes leaving a small space for the roller to turn freely.
