Simple latch to hold cabinet doors shut
DO NOT ENABLE SUPPORTS IF NOT USING CUSTOM SUPPORTS! There will be support material inside the hinge, and it won't move! In Simplify3D, you can place custom support pillars only on the sides!
I tried my hand at designing a hinge that swings 180° and works straight off the printer. All my other designs with moving parts all require assembly and bolts and whatnot, but I wanted this to look as clean as possible.
I've seen ones like this one http://www.thingiverse.com/thing:190118 and ones like this one http://www.thingiverse.com/thing:330151 that both print without assembly, and wanted to make one like that- but with constraints to 180°.
After printing, pull it off the print bed, give it a few taps on a hard surface, and give it a nice twist, and that'll free the hinge
