REmixed Prusa MK2 Threaded Bearing Spool holder w/filament guide

thingiverse

Remix from two other spool holders and slightly modified. Main holder rides on two internal bearings for a nice smooth roll. Can accommodate several spool sizes. UPDATE: Added new Spool Main assembly (v2) that beefs up the arm as well as where the nut inserts. If you're planning on printing this out of PLA, I would recommend going V2 over the original. Print Settings Printer Brand: Prusa Printer: Prusa Mk2 Rafts: No Supports: Yes Resolution: 0.2 Infill: 20-50 Notes: If your slicer has a "Supports from build plate only" option, turn that on. Post-Printing BOM You'll need some additional hardware to assemble this: 3 x M8 nuts. (5/16th also works) - http://amzn.to/2hdztwf Some 8mm threadded rod. (5/16th also works) - http://amzn.to/2gNYK2V 2x 608ZZ bearings.- http://amzn.to/2g6naFQ Assembly Attach the threaded rod to the main arm assembly, with a nut in back and a nut in front, securing the rod to the arm. Push a 608 bearing into each side of the inner spool threaded assembly. Slide assembly onto threaded rod and secure loosely into place with another nut. Assembly Video Optional Steps I like to sand down the grips on the spool holder as they can be semi sharp off the bed. 600-800 grit sandpaper around the edge of the grips helps.
