Wall Mount Spool Holder with Hygrometer

This wall-mounted spool holder is designed to be low profile while providing a place to mount the cheap round Hygrometers that can be found on the web and Amazon in either white or black. This spool holder will 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. The spool holder has holes along the bottom and back of the hygrometer to allow ambient air in.

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 the back. I also used a glossy PLA for lower rolling resistance, lower cost, and ease of printing.
