About this 3D model

Just a simple and small Filament Spool Holder for a wall. Most filament holders are so big and bulky. I simply wanted a smaller, narrower and yet sturdy version. (Carries 18 spools without a problem) Print with PETG!!! PLA will withstand the stresses for a maximum of 2 years. What you need: 28mm diameter round bar 2x M4 or M5 screws
