Snapmaker U1 Spool Guide

Snapmaker U1 Spool Guide This is a spool guide designed to prevent the spool from slipping out while rotating during printing, which occurs when the middle hole of the spool is large and the tension spring of the holder descends due to the weight of the filament. The insertion section is designed in three stages. 1. The thinnest section is simply made for length... 2. The second section is designed to fit snugly... 3. For the spool that goes all the way in, simply turn it in the right-hand screw direction to lock it in place.
