A simple design for reusing empty spools.
I designed it for sunlu empty spool in order to use refill bambulab spools.
Internal minimum diameter of the spool 72 mm, diameter of the internal hole is 55 mm.
Feel free to change it for other designs.
I've printed it on my artillery sidewinder x1 with pla, no supports required.
I printed the external base of the screw part with fuzzy skin for a little bit mor grip.
In order to use it you need to cut the empty spool in half, bambulab refills are a bit wider but they fit nice.
