About this 3D model

Edit: Fixed the .gcode file I got tired of the filament clips that are complicated to put on and are quite bulky especially since I change my spools on my printers very often, so I designed a clamp-like filament clip that attaches on the side of the spool and is easily removed and stored in the same place. Print Settings: Material: PETG would be ideal but should work in others as well Layer Height: 0.2 Walls: 1 Infill: 30% Rectiliniar Brim: If your print has bad adhesion
