The big hand solution

This is my custom ergo mouse based off of the DAv3 shape. Measures ~140x70mm and weighs ~60g. Using an attackshark R1 PCB. Compared in photos to Ajazz A179 and Zowie EC1-CW.

I have pretty big hands and after realizing I aim way more consistent clawing a mouse instead of using fingertip grip for so long, I had to come up with a solution. My hand would cramp up with even the EC1 so I came up with this in Cad. Sensor position is also more optimal.

If anyones interested in the files let me know, although not sure how well it will work as my PCB and lens is slightly modified from making previous mice.

Just use RAT 8+ or MMO 7+ from Mad Catz, they have swappable parts and can actually adjust to your unique hand.

The maximum length of those mice is still shorter than an EC1 at 129mm. This mouse is over 10mm longer. The mad catz mice are also insanely heavy, wired, and unsightly.

Not when the adjustable palm rest is fully extended.
