S-Hook (Heater radiator)

This is a S-Hook for your (bathroom) heater radiator, designed by me in OpenSCAD.
Alternatively, you can use the hook on any object where either hook can be attached to.

Because both hooks are slightly offset the hook will not easily slide of the radiator tubes.
Likewise, any object hung from the (smaller) hook will not easily slip off.

When printed in PLA and with just 30%-40% infill, the hook is still strong enough to hold objects up to 12 Kg (26 lbs).
