I job seems to be upside down but I managed to flip it in SketchUp (I'm new to all of this). ;-)
However, I notice there isn't any built-in-support for the hinge that you often see (and to a lesser degree, the single bearing) so wondered what others have used to best manage this please?
I've only tried adding support using Repetier / Sclic3r but it seemed to overfill everything! ;-(
