Neptune 3/4 pro/plus/max ball bearing spool holder, remixed to use 1x M6 bolt and nut instead of 1x M8 bolt
Spool Holder for your Elegoo Neptune 3 Pro (Plus, Max, and others) that uses ball bearings for smooth feeding.
Also lowers your machine by 2cm, making it fit into most small tents for 3D printers (e.g. Creality-branded ones).
You can mount two spool holders on each side.
