You can use one, two, three or as many as you want and create different patterns that can be changed anytime.

Or you 1 ore more completed hanger together with a half hanger to create your desired pattern.

Optionally, they snap together using magnets (two magnets of max 6mm x 3mm magnets are used per hanger)

I did tested my profiles with Bambu PLA with a weight of 2.5kg for a couple of hours and there was no deformation.

This hanger was designed mostly for clothes, but keys, small bags or other useful objects can be hanged on them.

I wanted to look as good and clean as possible on the wall/furniture and also be strong, so I've opted to gluing the parts together.

My profiles (designer) have different settings for some parts to be sure it's strong to hold as much weight as possible. 

There are two versions:

*with hidden screws.

*with accessible screws after you glue them.

Dimensions and hardware needed to install them:

Full diameter is 76mm.

Torus diameter is 16mm.

Each hanger needs: 2 screws of max 4mm and the head of max 8mm diameter. Optionally 2 magnets of max size 6x3mm.

Some glue.

Assembly instructions:

Easy to print, but you will need to glue together the parts. Take your time to arrange the parts and plan how you will put it together.

Be sure to arrange the magnets correctly before gluing the parts together, so that each hanger will attract the other part of the next hanger.

For the model with hidden screws, you will need to mount on the wall/furniture the back part and after that add the pivot piece and glue the top part over.

Be careful when you add glue that the glue will not go to the pivot piece and block the movement. Also try to align the parts well for a perfect look. Add as little glue as needed to hold them together strong.

The space between the holes needed to install them correctly. The space and alignment between two hangers is very important, to allow them to work together beautifully. 
52mm between screws for one hanger and 68mm between second screw of one hanger and the first screw of the next hanger.
