InMoov Solid Wrist Gear

None of the other gears I found on Thingiverse did the job. Too short. Too tall. Wrong servo hole size (too large), Hollow Teeth which were the whole problem to begin with. My wrist gear kept stripping teeth. Also, too small in diameter. Now the gear teeth fully mesh so there is no play, so, this one is working great!
