I needed some way to store my motorcycle helmets and so I created this simple but very practical hook.
Printing is very simple. The strength is sufficient from PLA, but you can easily use PETG. Print layer 0.2. Perimeters 2-3. These sets differ only in the screw holes, where one is for a flat screw head and the other is for a beveled screw head and with a hook for keys or a jacket.
