Filament Spool Roller Assy

thingiverse

My innovative spool holder relies on readily available, off-the-shelf 1-inch electrical conduit scraps to craft the roller itself. To assemble this clever contraption, print four roller blocks and carefully insert four high-quality 608ZZ (or equivalent) bearings into each block. Next, securely clip two sturdy feet onto the assembly. While I haven't yet had a chance to thoroughly test the stability of the feet, I did need to modify one of them slightly in order to accommodate my printer's 100x100 bed size, and I've since uploaded that revised design for others to use.
