Roller Filament Spool Holder

thingiverse

This holder, designed for MakerBot 8" spools, features a frame with integrated bearing spacers that utilize standard 22 x 8 x 7mm skate bearings and 5/16" x 1" hex bolts with nylon lock nuts. Local hardware stores carry these components. Print with supports for optimal results, including using corner coins already incorporated into the design. After printing, trim off excess support material and refer to the gallery for assembly instructions. The height (z-axis) should be precisely 1 inch or 25.4mm.
