Laser cut spool holder for 608 bearings

prusaprinters

I needed something more compact than the spool holders that come with the MMU2S. This one is designed to be laser cut. For each spool holder, you need to cut two sets and print out 8 washers. The washers go on both sides of the 608 bearing between the bearing and the wood. For 1/4" wood, you need 4 nuts and bolts. Bolt is 5/16 x 1". Print the bearingwheel.stl file from https://www.prusaprinters.org/prints/32949-adjustable-spool-holder-update and set the z height to 7mm, now this spool holder (so far) works with any spool I have! No more getting the edge of the spool holder wedged between the bearing and the holder. To add stability, run a piece of all thread through the spool holders.
