Basic Sturdy Wall Mounted Spool Holder

This is just a simple yet sturdy wall mounted spool holder. I wanted a wall mounted spool holder that didn't suffer from the typical drawbacks of similar wall mounted spool holders; mainly spool wobble when printing and not being optimized for strength. I designed it to be very sturdy, so it should hold up pretty much any spools that can fit on it, up to 78mm wide. Just make sure to print it as oriented in the print profile; it should be printed on its side. The area the filament spools rest and ride on has a 27mm radius, so the center holes of most filament spools will follow the curvature nearly perfectly, and this greatly reduces the “rocking” that typical spool holders with smaller spindles suffer from when printing. It's mounted with two #8 flathead screws. The holes are aligned vertically for mounting to a stud.Ideally, it should be printed with PETG. Take care not to over-tighten the screws; snug is plenty. The one in the pics was printed with anycubic gray PETG. Thanks
