Designed esentially for the TronXY X3, it could be a good option if your printer has similiar system as the Tronxy.

This spool holder improves your 3D prints because it is situated on the corner. And how can it improve the prints??? This way: On one hand the coil is aligned with the extruder during the whole duration of the filament roll... on the other hand, the filament is obtained in the best way from the roll and this way is tangentially (along the entire Z axis), which causes the filament to be fed without friction or sudden undesirable movements due to gravity forces. This fact makes your extruder calibrations to be stable along the whole filament and even if you change it. In add 2 ball bearings are mounted in such a way that makes the feeding process even softener, thus improving your 3D printing.

Designed for M8 threaded rod. 608zz ball bearings. No tolerances to avoid bad work of the bearings. Use the rod, 3 nuts and washer to insert the bearings.
