mouse pad to prevent mouse arm

This mouse mod helped me a lot! :)

This model was done real fast in Rhino3d (see file).
The print took about 1-2 hours.
Sanded it a bit to make it smoother, then heated the edges a bit (60*C) and pressed it in shape against the mouse. After letting it cool down I used hotglue to fix it to my mouse.

Before the mod I had pains in arm and shoulder and after just a few days they have vanished almost completely. I will update this if pain comes back, but so far it helped me a lot :)
I don't support the palm on it constantly but it is nice to be able to rest the hand in between moving around the mouse, for example while scrolling through lists or text.

Now I uploaded a larger version (scaled in height) for larger hands where the palm needs rest higher up.
