Just a basic solid skull I made to test out my 3D printer. It's not terribly accurate in terms of anatomy, but it makes for an interesting trinket.Made with SolidWorks 2018 using the nPower Power Surfacing plugin, so you'd need that to mess with the structure of the skull in SolidWorks. For people who don't use SW or don't have the plugin, I've included the .step file.
