About this 3D model

Hi, I wanted a simple spool stand for my shelf. So I created a sharp first version. Old version: Sharp edges, simple plain design. Slightly unsightly. New version: Rounded edges. Added small delimiting edges for easy connection of multiple racks to each other. It is thus possible to connect ad infinitum. It doesn't snap, it can stick, it doesn't stick together by itself. Faster printing, minimal filament consumption, good strength. Print profile tuned. For 2 spool. Or infinity spools with new version! It holds the spool perfectly. The spools fit perfectly and do not move. Please add a rating after the printout and, if possible, photos as well. :) I'm very happy that someone is using it.
