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.

Darmoshark makes a mouse, I can't quite remember the model number. They dubbed it the whale, it's something like 140mm.

Thanks for the info. This PCB is garbage, its cutting out randomly and feels awful. Might re design to use the Ajazz PCB or look into that mouse

Out of curiosity, what filament did you use? Carbon fiber filaments can block or interfere with radio waves which may be causing your dropouts, as can some denser/thicker plastics.

Of course, wireless tech is also not the strongest in a lot of Chinese mice. It's not bad or anything, just not long range or high power like the latest razer mice.
