Hook for 10mm, 12mm (1/2 inch) and 14mm steel rail handles

Well, a simple, elegant, cheap, fast printed and useful hook for 10mm, 12mm (1/2 inch) and 14mm steel rail handles that can be found in many kitchens and bathrooms.

Designed to be snapped onto the rail with the smaller opening so that it does not detach from the rail by itself.

Update 13.5.2022: added 10mm and 14mm versions, which are also very common for furnish handles
