V2 now available, raised the central webs so smaller spools can also be used without slipping into the middle
This is the big brother of my original roller spool holder, unfortunately it uses 8 of the 608 bearings this time (fidget spinners have had their day anyway right?). It has more fixing holes than its smaller sibling, including a couple that were designed for the CR-10 spool holder mounting position. Should fit most spools although if the filament goes right to the outer diameter of the spool's disks you'd be better off with the original Roller Spool Holder.
You will need to print 1x base, 4 x roller and 8 x peg
Should be fine in most materials (ok, not flexible, most other stuff though!)
Huge thanks to Tom for being the guinea pig.....sorry, valued and trusted prototyping technician, and also for the photos used here
