I made this to repair a toolbox that had a broken hinge, but was otherwise fine. Just print two to make one hinge. One has a cutout to clear the seam on the hinge line of the toolbox. the other does not.

The one with the cutout will need a small amount of support in your slicer.

I used M4 bolts to attach and as hinge pin.
