Filament reel centre and spindle

thingiverse

Update 06/03/2017 Found that after a few reel changes and using the 3D printed spindle, it was somewhat loose. My answer was to drill a 3mm hole in the outer cone and then use a tap to give it a good thread and used a 3mm plastic screw. Only finger tightness is needed, and the cones now sit with no slippage on the spindle. Needed something to centre the filament reels I have. The centre of the reels are mostly different sizes, so came up with this little paraboloid shape in Tinkercad. It can handle my reels which have central holes from 30mm up to 55mm. Then added the hole for the 8mm threaded bar. Soon found out that the threaded bar likes to rotate and trap the spool against the spool holder, making the printer struggle to get the filament. Tinkercad again came to the rescue with the 8mm x 165mm spindle. Found that once you insert one cone onto the reel and then add the spindle and then add the last cone on the other end, the reel still likes to travel. Ending up with the reel rolling around the work top. Maybe I should make the spindle a little longer. So used a couple of mistake cones which I had onto the spindle, one on each side, and this keeps the reel centred on the reel holder which came with the 3D printer.
