G305 lightweight "Alien" shell

thingiverse

This is a custom designed shell for the Logitech G305 wireless mouse. The total weight of the parts will be approximately 20g, depending on print settings and material, excluding the PCB, buttons or battery. It accommodates a standard AAA battery and all required screws are those from inside the stock G305. Also added is a base version with no thumb rest and flat sides only. Now featuring PCB mounts as well that were forgotten previously (oops). And the buttons have been modified with a reversed AAA battery socket for improved cable fit in some cases. Tips: * The base should print mostly fine without supports, although there's a custom supports version available for the one place where it has issues. Printing with a brim is recommended to enhance adhesion in certain areas. * The wheel must be printed upright (like it does in the mouse) or at a slight angle to ensure the bar remains as strong as possible. The smaller end is slightly oversized so that you can sand it down and achieve a tight fit into the scrolling assembly. Sanding and smoothing the larger shaft will result in smoother wheel operation. * The buttons may be a bit too stiff and press down on the switches too hard, keeping them pressed down unnecessarily. To resolve this, you can sand/file away the bottom of the pad that hits the switch to make it lighter or add a spacer between the buttons and the frame where they screw together (a tiny folded piece of paper works great). * The back plate is optional. If you do choose to use it, don't screw the buttons and the frame together before adding the back plate, as it uses some of the same holes. Other notes: * You may want to consider using slightly higher clearance mouse feet because the base may warp and become slightly bowed when assembled. * Sand the bottom of the base and the edges to ensure they're smooth and won't snag on your mousepad. * Also sand any surfaces where you'll be touching the mouse, as it will feel less slick and slippery then. * You can replace the battery without opening up any part of the mouse. * Feel free to modify the design to suit your hand in any 3D modeling application.
