I was very intrigued by this design. I printed the gears using FormLabs tough resin and the rest of the parts in clear resin. I used the BoltGen plugin for Rhino 5 to generate bolts/threads and printed them with the tough resin too, so no need for metal bolts. I also created a pyramid base and drive shaft, and added a motor controlled by an Arduino board. To make it more interesting, I used the DHT11 digital temperature and humidity sensor to control the speed of the motor in the 65-75F range. Now I have a very cool object on the desk that provides a visual indicator of room temperature!
