Hanger for filament spool

I couldn't find suitable hooks for my filament supplies so I made them. There are two types, one (white) is stored behind the other and the other is next to each other. See the pictures. It is possible to hang only one spool on one hook. The hook is made for a 15.5mm wide tube. Layer height 0.2 Support: yes Nozzle: 0.4 Material: PLA Weight/Consumption: 22g
