Kensington Expert Trackball Wedge(s)

thingiverse

I use my keyboard and trackball on a shelf below my desk level to enhance my typing experience by adjusting the angle at which I type. Recently, I replaced my Kensington Orbit with an Expert Wireless, but found it no longer comfortable. If there was a way to use it upside-down, it would probably have been acceptable, but I couldn't figure out how to do that. I discovered KoolMees' wedge on Thingiverse and thought it was a good starting point, but it wasn't the exact right angle for my needs, and I didn't require side-to-side tilt. I found an online model of the Expert and used it to create wedges at 5°, 10°, and 15° that interlock with each other and with the Expert using its normal wrist wrest holes, so you can create any angle you want from 5° upwards in 5° increments. I also made one with a little wrist wrest extension, and used it for my final solution at 30°.
