Balcony Privacy Screen Holder
I used the concept of off center axis to create a lock that keep the sheet tight to the bars.
The size of the square bars of my balcony are 1cmx1cm. You can easily modify it by changing the scale of the object.
I have upload two files : One with only two parts, but require support. And the other one with three parts but don't need support.
I also design holes and the axe with lot of loose, because my printer is not very precise...
