To make the hinge of it, I put nails into the deep freezer. When the nails shrinked in size because of the cold, I took them out of the deep freezer. I inserted them into the hinge. When they reached the room temperature, they became harder to remove, which is what I wanted.

I 3D designed it using @SolidWorks. I 3d printed it with @proto_pasta Carbon Fiber filament using @makerbot.
