Filament Spool Solution – Prevents Issues

Tame your filament spool! This accessory slides onto the spool and reduces friction on the spool holder, preventing poor filament winding—especially on cardboard spools like those from Elegoo. Some products allow multiple units without increasing the price; please send a message. Price is non-negotiable! I only sell in person in the Barreiro area and surroundings. I can ship by mail, but only with advance payment via MB Way, and shipping costs are borne by the buyer. filament organizer spool holder 3D printer parts printing support filament rod filament issue improve print quality 3D accessory printer maintenance filament roll
