3030 minimal spool holder

thingiverse

This support system is designed for attachment on 3030 profile-based spool holders with the goal of facilitating spool rotation by reducing surface friction, making it easier to swap out spools, and guiding the spool into place. The supports are used in pairs and clipped directly into the 3030 profile. This mounting arrangement adapts quickly to different spool widths. To achieve this, you need to print a few parts that will securely attach to your spool holder.
