Ball Bearing Spool Holder

thingiverse

I tried some new, inexpensive filament (Dazzle Light) and liked it a lot. However, their spools have a huge ID and the sides were too thick for my existing spool stands. These work very well for it and use these super cheap ball bearings from Wish. https://www.wish.com/product/5864a648def90b4faa7614ce (In case link is dead, the bearings are 11mm OD, 5mm ID, and 4mm wide) I used qty.4 10-32 x 1" machine screws and nuts. 1" was a little too long so 0.75" may look better. DON'T OVER TIGHTEN THE SCREWS!!! The only issue I had was that the shelf you see in the picture is very slick so the stands tend to slide a little while printing. My quick fix was to add the binder clips you see. The spool spins very freely so there isn't much force trying to pull it off the shelf. Anything to add some friction should be enough to keep them from sliding. Thanks!
