I was wondering if there are any mice with fans built inside of the mouse, because my hands get very sweaty while I use it, and I was looking around but all I could find was a mouse but with a fan attached to the front of it. If there aren't any mice like this, is it possible to mod my current mouse to have a small fan inside?
I have seen production mice like this before, but they are all old.
You could accomplish this by buying a USB-powered fan small enough to fit inside the chassis of a honeycomb mouse, gluing it inside the chassis facing your hand, running the wires for it down your mouse cable (in a paracord for example) and splitting them off onto a separate USB connector at the end.
