Hooks for Camper / caravan awning

Redesigned the hook so it would print better then his version.

Now you can you use it also for hanging towels.

hook for tent rail

In addition to this, see also: https://www.printables.com/model/555615-clamp-for-camper-caravan-awning

for clamping stuff.

The change I made is mostly the the printability from original. My hook has possibility to print without supports and has layers of the print in the best way to have greatest strength in the print.
