Tevo Tornado Spool Holder

After a few tries I got this to work. Found some sliding door rollers cheap in the hardware store and learned how to draw this up in Fusion 360. The bearings measure 25mm diameter and 7mm across with an ID of 4mm. The spool fits perfectly into the groove on the roller. Just place a bearing on each post and put 2 together. Need to print 4 parts for the full set.
