Hey all. I am trying to get a model printed that has many intersecting meshes. I am running into a problem where small parts (such as little nuts and bolt-heads) are not quite intersecting with the rest of the mesh: either lying flush with surface or slightly apart from the surface. This problem is only detected after an order has been made and the model is about to be printed. I need to fix all these errors before my deadline, but I have no idea how to detect them. Searching for them manually isn't really an option given the complexity of the mesh. Is there a script or function that can detect these errors? I am using blender but I am willing to switch to another application if it means I can get this fixed and done. Here's an example of the problem, in which the white, blue and green parts are supposed to intersect but do not.
