I printed an AMS Lite stand by another creator, and my filament was rubbing and not properly retracting on color changes due to the friction on the stand, so I made this spacer to push out the filament a little. The dimensions are 55mm inner diameter, and a 10mm wall, so an outer diameter of 75mm. There are two versions, 5mm width and 3mm width, text included on the top of the spacers.
Just push this spacer on before your filament and you're good to go, feel free to edit the file to determine what spacing you need.
