Adjustable Tabletop Spool Holder

thingiverse

A compact, tabletop spool holder which has a tool-less width adjustment allowing for various brands of spools. Uses 4x [625ZZ bearings](https://www.amazon.com/gp/product/B01M6BY2MU/) that have 5mm ID,16MM OD with 5MM width, all other parts are included. This holder is designed for printers that don't have their own spool holders, and don't use bowden setups (although you may find this works for yours, I haven't tested it). Originally built for a Printrbot Maker's edition, which it served well. The printer may be gone now, but I decided to share this spool holder so others might benefit from it. Parts BOM: 2x Side Panel 1x Threaded Rod 2x Adjust Knob 2x Knob Capture 4x Bearing Mount 4x Bearing Pin 8x Mount Pin 8x Bearing Washer (optional but recommended to reduce friction) 4x 625ZZ Bearings Construction Notes: -The lips on the knob captures may print a little funky for you as they are significant overhangs, but if you cut it flat with a razor blade it should hold just fine. -It is recommended to assemble the pins using either superglue or hot glue when assembling the pins, as they may not fit tightly. The longer pins are for the bearings. If I was smarter I would have made them all the same size, but alas. -You may want to add rubber feet to prevent the holder from sliding, if the surface it's on is low friction. Not recommended for tangled/haphazardly wrapped filaments as the pulling forces spike and can pull the reel off the holder. This rarely happened unless I was using really jank filament brands but you have been warned. Sorry for the lack of a picture, I only made two and I gave them away with the printer. Can confirm this design works, at least!
