Magnetic/tabletop Spool Holder with bearings. ADJUSTABLE

Changed the design slightly for my cr10. Can be used with or without magnets. Was going to make a clip on version but then it would be limited to the cr10/wanhao control boxes. Highly recommend printing the rod as will for stability.
Uses 4x 608ZZ bearings(standard skate bearings)

Magnets are 1/4 x 1/8 and my specific ones were bought here:
