This wall-mounted spool holder is designed to be low profile and accommodate spools up to 72mm wide (Polymaker, Prusa, Paramount, etc). It is meant to be mounted using Bore-fast screws that are drywall mounts that do not require a separate drywall anchor. They are fast and secure.
Print at 0.2 layer height, grid or gyroid infil for strength, with 15% infil. I used 3 perimeters for strength around the screw holes. No supports needed if printed on back. I also used a glossy PLA for lower rolling resistance, lower cost, and ease of printing.
Update 17 Aug 24: Added “Wide” version that will accommodate 2kg Prusament Spools.
