Logitech M575 Trackball Ergonomic Angled Base 30°

Only the mounting points were copied from the Doc Taylor's model. The entire base is new, fitted closer to the actual base profile of the M575, with a simpler solid shape because I didn't like the honeycomb-with-branch thing the original had. I also integrated storage for the mouse's two accessories, the wireless dongle and the original battery cover. The other models I've seen neglect to have a space where they can be stored to not lose them. In losing the cantilever design it also makes this model easier to print, without a potentially ugly-looking underside to the main platform.

You probably want to cut out some foam or other grippy material to go onto the underside of the base in contact with the table, both to protect the surface and stop the mouse from sliding around with use.
