Does anybody know of any MX Master 3 modding forums or other resources? The firmware and electronics in these things are fine, but these mice are one size fits none. In my case: way too small. I probably need one that's 2 times the size + preferably vertical. I was thinking of doing a mod where I convert an MX Master 3 to a much larger MX vertical type thing. Shouldn't be too hard, but if I can think of this someone probably already did it. Right?
