Sturdy hook for towel radiators

A simple hook for towel radiators. It can be used for towels, hair driers and other stuff that you want to hang from the radiator.
Even heavier things like bathrobes or big towels are no problem, the hooks are really sturdy.

The hook snaps onto the radiator and is locked in place with a screw.
The curvature of the hook mimics crane hooks, it grabs onto things really nice. Hanging a towel from its edge works really easily.

Measurements of the radiator: tube diameter 22,5mm, the gap beteween the tubes measures 19mm.

Because radiators are hot (duh), the support leg of the hook can bend over time and get a little loose. Thats the need for the locking screw.
You also need: M3x30 screw (or longer) and M3 nut, preferably selflocking.
