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 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. Sanding and smoothing the larger shaft helps the wheel spin smoother. * The buttons may be a little too stiff and press down on the switches too hard. keeping them pressed down. You can sand/file away the bottom of the pad that hits the switch to make it lighter or add a spacer in 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 want to use it, don't screw the buttons and the frame together before adding the back plate, because it uses some of the same holes. Other notes: * You may want some slightly higher clearance mouse feet, because the base may warp and become slightly bowed when it's assembled. * Sand the bottom of the base and the edges to make sure it's smooth and doesn't snag on your mousepad. * Also sand any surfaces where you'll be touching the mouse, 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 modelling application.
