Features Great Features: Good load bearing performance, sturdy and long service life, smooth sliding, anti jamming and winding, easy to use. Wide Application: The 3D printer spool holder made of premium ABS material, it ensures stable spool feeding, thereby reducing all resistance on 3D printer wires. Easy to Operate: The filament holders are pre assembled brackets that do not require tools and are easy to install. The bearings may become a bit stiff during first use. Please lubricate them more as they will run well. Smooth Bearing: The silicone anti slip pad has better adhesion than before, making the bracket less prone to sliding. The long wire spool bracket bearing is covered with a collar to prevent the bearing from getting stuck due to oxidation, ensuring smooth operation and reducing all resistance on the 3D printer filament. Suitable Material: The detachable printer filament holder is suitable for all spools of any size and all filament types, especially for PLA, ABS, TPU and other 3D printing materials, with the most common being suitable for 1 kg and 1.75 mm PLA spools.
