Small (54mm tall) hinge I used to mount a blank picture frame to the outside of my printer enclosure as a door. I used 2 of them to support the frame. The design allows for the hinge to be lifted off easily, which I do often for disassembling the enclosure.

Note this won't be as strong as a hinge using a bolt or raw filament to pivot on, and will only work for relatively light tasks.

Holes are 4mm diameter.
