Old fashioned hinge

thingiverse

Print at any resolution, the rougher the better. Make sure you use supports. When finished gently flex the hinge to break the support holding the pin in place. You may need to clean up a little of support at the base of the big part of the hinge as this may catch when you are moving the hinge. Works well. use a 90% infill and the hinge will be very strong. Paint with some hammertone paint if you want an old fashioned look.
