Simple spool holder bracket for cupboard

Simple, fast to print bracket for use with 19mm dowels or rods. Prevents your spools from rolling by themselves, allowing you to store them vertically inside a cupboard/shelf/closet. Includes 3.5mm holes for the dowels and a 3mm hole to mount it to the sides of your cupboard. In my case, I hotglued it to the sides as is not its definitive mounting point.
