Hi Danny, yeah STL or OBJ are some of the most common polygon file formats so hopefully it would support one of those. I'd think it would support STL at least since that is the single most common polygon format involved with manufacturing.

You'll probably want to use the "Divide larger than" setting when producing the mesh so that more evenly sized polygons are created, like this:
