I have become a claw grip user since buying this mouse and I can't help but feel hamstrung by the left side of the back being so close to palm's thumb muscles. When switching from arm to wrist aiming on low sens and anchoring to the mouse pad with the heel of the palm, Y-axis mobility is severely restricted because of this. I've thought about buying a second mouse just to use for competitive FPS games which is the only genre where this restriction feels bad. I use a much higher cm/360 everywhere else. I do not have small hands. I can span an octave and a half step on a standard size piano.

But I don't want to use a second mouse. I love this mouse. I've used it for so long, I've replaced the switches once they started failing as my warranty was long gone by then. I only want the shell of the Z to suit my needs. There are two ways to accomplish this. One is cutting, sanding, and using bondo to modify the existing one. I have the skills and equipment,  but this is still terrifying because I only have one and mistakes will be difficult to recover from - and I don't have a backup mouse to use while I wait for things to dry. The other is 3d printing a new shell after adjusting the shape in CAD. I could spend ungodly amounts of hours designing a copy that fits, or you could grace us with a file. Please, I implore you Swiftpoint - give us an STL of the shell.
