This model is for makers who have a Ikea skadis pegboard and want to keep their filament in a nice and neat way. When you have printed these out you just SLAM two 13mm (or half inch) wooden rods in there. I recommend printing 2-3 mounts and placing the spools with the most filament in the edges, and the ones with the least amount of filament in the middle to avoid “Sagging.” No screws needed.

These are the wooden rods i used: https://www.silvan.dk/hornbaek-rundstok-fyr-13x1200-mm?id=5400-9700859&gad_source=1&gclid=CjwKCAjwo6GyBhBwEiwAzQTmc56o9sqk_bn8WpHQe8CWCKDzCC02UKzrkmdTVQteaT1jtubKfL7p9RoCz00QAvD_BwE
