Simple Screw-Jaw Miniature Painting Handle

Inspired by Aktalion's Miniature Painting Handle ( https://www.printables.com/model/360470-miniature-painting-handle ), but built from the ground up. I designed this version for painting ~75mm miniatures, mainly Monsterpocalypse monsters, so I've included jaws specifically designed for official Monsterpocalypse bases (original clear plastic and new 3D printed). I find this particular shape to be most comfortable for this size of miniature (I prefer a different shape for smaller miniatures; I don't really understand why).
