Outputting an STL file that contains multiple objects for import into Blender
I want to print a object that looks like a flat board with a set of matchbox-like lumps on top of it.

For some reason, my larger prints, or rather the ones that I create, have this "dotted" line in them. And, that line usually splits into two pieces.

Let's say I've made a 3D scan of my face and managed to get that into FreeCAD. How might I then create an object (it's a mask, okay?) that conforms to the shape of my face, with a given thickness, such that I can export and 3D-print that part…
