Adjustable Spool Spindle (ASS) for 21.5mm Plumbing Pipe

thingiverse

Update 31/05/2018 New design fits perfectly around 75mm diameter center hole of filament. Update 21/02/218: Added cutaways to reduce material usage. Same amount might be used due to required supports, untested so far. Update 26-01-18: Printed and tested successfully. Assembled well, keeps everything in place. Took about 1 hour and a half to print at 0.2 layer height. Update v3 24-01-18: Simplified design now consists of two parts. Yet untested. Update v2 24/01/2018: Added single-sided threaded spindle, so you only need one each of the items instead of double-threaded cones and nuts which required printing two of each. Needed a custom spool holder made out of 21.5mm plastic plumbing pipe, but most filament spools have a hole diameter between 45mm and 65mm. This caused issues as the spool didn't turn well and put pressure on the extruder to get the filament off the spool. To fix this, I designed this spindle to act like a bushing for the filament spool. To print: 1 Spindle 2 Cones 2 Nuts
