Split filament refill spool with locking ring and removable flange

Measure the inside diameter and width of your secured refill coil and the axle of your spool holder. The printed set contains the core with its fixed flange, a removable flange and a threaded locking ring. Set the core diameter with suitable insertion clearance, clear winding width, flange diameter, axle bore and flange thickness. Slide the still-bound coil onto the core, fit the second flange and tighten the ring by hand. Remove the retaining ties only after the coil is fully contained between the flanges. Each flange has six viewing holes. Check free rotation, edge clearance and ring retention outside the printer first. The spool is intended for suitable external holders; compatibility with automatic feeding systems or branded refills is not promised. Do not use it in heated dryers. Adjustable values: Winding-core outside diameter: 55–85 mm; Clear width between flanges: 35–70 mm; Flange outside diameter: 150–210 mm; Axle-bore diameter: 8–30 mm; Thickness of each flange: 2.5–4 mm.
