This is one of my first designs ever that I made when enclosing my very first printer back in 2016. I tried real metal hinges but they had too much play in them. These are self-centering and actually quite durable. The B version can be used on a door and lifted off.

They are designed to be very tight. I have provided a slightly looser version named + if you have trouble getting them to work. Screw holes are Ø4.5mm

Also included is a Decorative Corner for the enclosure side panels.

Print with high cooling at 0.15 layer height.

I have printed these in most materials I have tried just for fun. PLA, ABS, PETG, Nylon, all work well.
