Simple Table Hook to hook your bag or anything you want. 

Suitable for table around 2 - 2.5 cm thick. It would flex a little bit, don't worry. 

The hole is 1.9mm, which would be suitable for 1.75mm filament (you can use other color). 

After the body and the arm printed, use a pieces of filament to thread into to hole as example : 

If it's loose, you can use something sharp and punch both end, it will keep that “hinge” in place.

Please use PETG for best result. 

I have another version that have the hinge built-in, however, setting up the support for levitating arm inside the body prove to be quite a challenge for smaller printer, I'm still working on it. Please send me a message if you are interested.
