I made an enclosure out of 5mm polycarbonate but did not like the hinge system. It did not feel robust and I had a lot of gaps and the door pinching on the frame when opened.
I printed the original design but the hinge pin broke, so I modified it to replace the hinge pin with an m3x25 bolt.
Other hardware I used:
4x m3x10 to mount hinge to frame
8x m3x8 to mount door hinge to enclosure door.
The author remixed this model.
Modified the part that connects to the door. Added screw holes and replaced the plastic pin with a hole that fits an m3x25 bolt. I used 4 socket cap bolts for the hinge pin and 4 nuts to make sure the doors stay on.
