A must-print for new printers H2 Series Filament Spool Bearing Holder low resistance ultra smooth Print in Place one-second installation super convenient

Hello! This is my first 3D Printed work. After 7 revisions, the ready-to-use smooth holder is finally born!

After printing, the bearing should be able to rotate. It is highly recommended to add a few drops of lubricating oil or WD40 inside to double the smoothness!

- The bearing size has been carefully adjusted so that it can fit most common filament spools, including models with smaller inner diameters like large paper spools.

- If necessary, a bushing can be snapped on the outside to prevent the filament spool from sliding off (e.g., when the filament spool unwinds).

- The purpose of the bushing is to minimize the wobbling of the bearing and the filament spool. During installation and removal, the bushing needs to be placed diagonally below, close to the machine, allowing the bearing to slide in and out smoothly. After installation, the bushing can be pushed to the left into the bearing for a more aesthetic look, but it might require a slender object to push it out during removal.

Hope everyone enjoys using it! Any feedback and suggestions are welcome, and I will continue to improve it! Looking forward to my first like and boost!
