Welding Gas Tank Hook

I wanted more storage on the welding cart, contemplated buying a Hel-Hook but found a design on Thingi that fit the bill. Only problem was I'd have to remove my gas regulator to install it. So I remixed it to add a removable section of the ring. Does this weaken it? Yes, but this hook is intended to hang lightweight things like cords, welding hoods, and maybe the cylinder cap so it will still work as intended. If you want to hang heavier things than I'm planning, go with the original model. 

I'm using DURAMIC 3D PETG Filament
