Hook

This is a simple design: a hook.
At the last moment I had an idea, I do not know if it's interesting, I do not know if it's a good design, but I wanted to share it because it may be useful for some people who do not have hands. Anyway I want to refine and improve it soon.

I've updated the hook. Now the hook is having an opening to grab things thanks to a wing nut that presses. I put silicone on the hook for better grip, I'll upload a tutorial soon
