A simple but stable hinge for systemprofile 2020 and 3030. The hinge is made for mounting a 3mm plate. But could be adjusted in the Step file.
The counterplates hold the nuts.
It is most reliable to print the hinge standing together as designed without support. One M3x30 screw is required to connect the two parts of the hinge.
