Yet another spool holder for the Wanhao D6. This uses the factory nut and threads into the same spot on the printer.
I created this as the existing bearing spool holder did not work as well as I would like. This holder has guides on the inner and outer part of the hub. I have tested it with up to 2kg spools and it works great.
Beyond the printed parts, you will need:
1x 5" long 5/16 bolt or an equivalent length of all thread
2x 608 skate bearings.
1x 5/16 nyloc nut (2x if using all thread)
1x 5/16 washer
The washer goes between the roller and the printed nut holder to act as a spacer. Just tighten the bolt enough to take up the slop but don't over tighten. If you over tighten the roller will not move smoothy.
