Makerbot Z18 Top Mounted Spool Holder

thingiverse

As with all Makerbots this has the annoying old-fashioned filament tube that causes 90% of filament jams. So I made this top-mounted spool mount that doesn't need a tube and feeds the filament directly to the extruder. But since I hate spending 20 hours printing a silly spool mount for my printer, I came up with this one, which prints in less than 4 hours but requires 6mm & 8mm Round tubes (carbon, brass or aluminum), thus cutting print time by less than 1/6th. Almost no friction and no ball bearings are needed. I've also added 2.5mm holes if you need to add M3 mounting screws. Note: Print twice (left and right sides).
