Snapmaker U1 Alternate Spool Holder

This is a reinforced alternative spool holder system for the Snapmaker U1, designed with one priority in mind: stability (Tested with MarsWorks aluminum spools ) This is not a quick-swap or tool-free solution. Instead, it uses a locking hub and hex-tightened spool nut to create a much more secure mounting system. Once installed, the spool is held firmly in place with minimal wobble, making it ideal for longer prints and consistent feeding. If you’re tired of loose or inconsistent spool mounting, this fixes that. If you are using a Snapmaker U1, go directly to “Raw Model Files” to download the correct files.
