Universal Spool Holder with Fidget Spinner

myminifactory

This is just a normal table top Spool Holder designed for free spool movement. Using an old fidget Spinner to get the ball bearing functionality at central axis for smooter movement. UNIVERSAL spool holder that accomodates spools of all shapes and sizes. Print in place with no supports. But you have to enlarge the "support-sph.stl" by 2.8% to get the right size. No sanding required, everything fits perfectly. The holes in support-sph are for M3 screws, but I am using M2 with washer and nut as in images, as it makes it easier to tighten and loosen the grip on spools using a normal tweezer.
