Filament spool power winder
thingiverse
This is a simple conical drill attachment, to quickly re-spool a bunch of filament. Print 2 of these, insert M8 nuts and use a long screw or allthread. I added a 0.2mm membrane at the bottom of the hole so bridging is easier. Added finger holes to reduce material and make it easier to tighten onto a spool.
