So we don't currently have the ability to specify the printing orientation for our models. However, I'm wondering if there are ways to play the probabilities to get the correct orientation.

Specifically, I'm planning to print many copies of a small object, and I can choose the orientation of each of them in my model. I could put a third of them with 'up' pointing along the x axis of my model, a third pointing along the y axis and a third pointing along the z axis. If I did this, I know that two thirds of my models would come out correctly. Alternatively, I can have all of my models pointing the same direction, and hope that it is printed in the correct orientation. For both of these plans, the expected proportion of good models would be 2/3 of them.

Here's another thought: What if I arrange the objects in a way to maximise the chance that it will be printed in the correct orientation? Suppose for example that I arrange the models so that they are lined up as a long stick, rather than being in a cube. In fact, suppose that my stick is so long that it won't fit into the machine other than in exactly one orientation. Then knowing which way this has to appear in the machine, I can choose the orientation of each of my objects in the stick so that they will definitely be printed correctly.

Would that be evil?
