Quick Fix Spool Holder

cults3d

I needed a filament spool holder that fit every spool, made quick and easy spool changes possible without tools, held the spool tight while minimizing friction. I took inspiration from the double countersunk spoolholder with ballbearings, added a large thumbwheel, and combined the wheel and front spool insert into one part to make it even easier to use. To achieve this design, I made the thumbwheel hold a long (30mm) M6 nut and widened the two front bearings (13 mm inner diameter) so they run on the center cylinder of the thumbwheel instead of the threaded rod directly. Now you can remove the combined front part with one hand only and fastening or releasing the spool is much easier. The momentum of the big wheel allows a good turn, which keeps turning all the way in or out without needing a locking nut or wrench. Hand tightening the wheel is enough, thanks to the low friction of the ballbearings that prevent the screw from loosening itself.
