Auto-Rewinder Mod for Creality Space Pi x1 & x2

Love Vincent’s Auto-Rewinder system but wish it worked seamlessly with your filament dryer? The wait is over. Designed specifically for the Creality Space Pi x1 & x2, this mod utilizes the core spring mechanism from Vincent’s Integrated Auto-Rewinder system to bring managed tension to your drying setup.

Best of all? This mod requires zero physical modifications or permanent alterations to your Creality Space Pi x1 & x2. Simply plug it in, and you’re ready to print.

**UPDATE 24/04/2026:** The left and right brackets now include a patch to install 1mm double-sided tape to further secure your brackets into the Space Pi.

How it Works:

This system prevents filament from slackening during retractions or tool changes, significantly reducing the risk of tangles. It is designed to provide one or two turns of light tension—just enough to keep the filament seated perfectly on the spool without putting any strain on your extruder.
