Cobblebot Little Monster Spool Holder

pinshape

I crafted this Spool holder specifically for my Cobblebot Little Monster 3D Printer. It relies heavily on a 1/2"x12" threaded rod, four nuts and four washers, along with four of the M3 x 10 and M3 T nuts. The design mounts securely to the 8020 extrusion. To assemble it, you'll need to print two of the clamp parts. First, place one of the nuts and a washer on the threaded rod, followed by one of the clamp parts, then the filament spool, next the other clamp part with a washer and finally secure it all with a nut. You can easily adjust the tension to your liking so the spool will turn smoothly on the clamp parts.
