G305 lightweight "Alien" shell

This is a custom designed shell for the Logitech G305 wireless mouse. The total weight of the parts will be around 20g, depending on print settings and material, not including the PCB, buttons or battery. It fits a standard AAA battery and all the screws needed are the ones from inside the stock G305.

Also added a base version with no thumb rest and just flat sides. Now with PCB mounts on it too that I forgot last time (oops). And the buttons with a reversed AAA battery socket, for a better cable fit in some cases.


Tips:
* The base should print mostly fine with no supports (there's a custom supports version for the only place where it has issues). Should probably print with a brim, to make the adhesion better in some places.
* The wheel should be printed upright (like it is in the mouse) or at a slight angle to make sure the bar is as strong as possible. The smaller end is slightly oversized so that you can sand it down a little and get a tight fit into the scrolling assembly
