Whats contained: you will get 1 set black 3D printer spool holders, include 2 pieces separated holders, compatible with PLA/ABS/TPU/Other 3D printing materials.
Smooth bearings design: filament spool holder adopt the latest technology, the silicone anti-slip mats has better adhesion than before and the holders are not easy to slip; The filament spool holder bearings are covered with a ring to prevent the bearings from becoming stuck due to oxidation, and the bearing runs smoothly, reduces all drag on your 3D printer filament.
Easy to use: the filament roller is a pre-assembled holder, no tools needed, easy installation and quick installation, the bearings may be a bit stiff when you first use, please lubricate a little more and they will run well.
Strong and quality: the 3D printing spool holder made of quality metal and plastic, stable and reliable, the size is approx. 168 x 24 x 35 mm/ 6.61 x 0.94 x 1.37 inches (L x W x H), you can use it safely.
Wide applicable: adopting quality material which creates a consistent flowing spool that reduces all drag on your 3D printer filament, the separated holder fits all spools of any size and all filament types, the most common works well with 1 kg and 1.75 mm PLA filament spools.
