This sidemounted Spoolholder for the Bambulab X1C is remixed for Compatibility with an AMS. It uses the original mounting Hardware, as well as the Spool Roller of an Ender 3 S1/S1 Pro.

I added a cutout for the AMS connector cable, as I want to use both the AMS and the Spoolholder without changing anything up.

I printed this laying down, to avoid testing my Layer adhesion :) - might work standing up as well

i used 4 walls, 20% gyroid infill at 0,2mm layer height with pla. i reccomend different materials like PLA-CF, ABS or ASA though, as PLA tends to creep under load.
