Turn the crank and the filament moves neatly from one spool to the other. Two gears, not a single metal part.
A cardboard spool that won’t fit the AMS, leftovers from several rolls you want on one spool, or a new roll to split in two? Put the donor spool on one stand, an empty one on the other, and turn the crank. The filament winds evenly, with no twists or knots.
Inside is a real gear train: the crank turns a 40-tooth gear, which drives a 20-tooth one, so the receiving spool turns twice per crank turn. Respooling goes twice as fast and your hand doesn’t tire. The donor spool spins freely on its axle in the slots of the second stand.
All 11 parts are printed — no metal parts. The two stands lock together, the axles tighten with star nuts, and spools come off in seconds. Fits standard spools, including Bambu Lab.
Spin the assembled respooler in 3D: the “In action” button shows the mechanism at work.
