Here's a printed-assembled hinged box.

It is really a test/demo of a new hinge library I've been building using an improved "unit hinge" similar to my thing 83033. I'll be releasing the OpenSCAD/Customizer library to make hinges shortly, but since there has been a lot of activity on thing 83033 lately, I figured I should let folks know what's coming....

Instructions

This should be a straightforward print using PLA extruded 0.3mm or finer. This STL file uses a 0.3mm gap between parts that shouldn't be connected, but that's actually a parameter in the OpenSCAD library this demonstrates.... The only aspect that doesn't necessarily print well is the little post used to keep the box closed; it's so small that the extruded filament tends to slosh around a bit, deforming it enough so that you might need to do a little filing to clean it up.
