You’ll get 1 set of black 3D printer spool holders, 2 pieces of separate holders.
The filament spool holder adopts the latest technology, the silicone anti-slip mats have a better grip than before and the holders are not easy to slip; The bearings of the filament spool holder are covered with a ring to prevent the bearings from jamming due to oxidation, and the bearing runs smoothly, reducing any drag on your 3D printer filament.
The filament roller is a pre-assembled stand, no tools required, quick and easy installation, the bearings can be a little stiff when first used, please lubricate a little more and they will work fine.
The 3D printing spool holder is made of quality metal and plastic, stable and reliable, the size is about 165 x 24 x 30.6 mm/ 6.49x 0.94 x 1.2 inches (L x W x H), you can use it safely.
The adoption of a quality material that creates a constant rolling spool that reduces any drag on your 3D printer’s filament, the separate holder fits all sizes of spool and all types of filament, the most common works well with 1kg and 1.75mm PLA filament spools.
