Mosaic Feet & Spool Holder
by bwevans, published
A re-written version of the feet that ship with the MakerGear Mosaic and the spool holder feet to match to make one version of the many four bearing spool holders around Thingiverse.
Designed using M6 rod and 626 ball bearings although the source file could be easily changed for M8 rod and 608 bearings.

To build the spool holder, you will need the following:
2x 150mm M6 threaded rod 2x 125mm M6 threaded rod 4x 626ZZ ball bearing 16x M6 nut 20x M6 internal tooth lock washer
Assemble as shown, making sure to place a lock washer in between the inside of the foot and the bearing. Inside dimensions are approximately 76mm x 100mm between feet although this is not mission critical. I find it works especially well with 1.75mm filament to feed the filament from the bottom to stop filament unraveling.
