I kept stumbling over how to make the compliant springs move in a linear motion, but every idea was bulky or too delicate. I went back to the proverbial drawing board, which is to say I took a hot shower and kept a dry-erase board handy.
The idea I want to try next is unique because it uses water and floatation instead of mechanical springs or elastics. The concept is that I will float a cylinder inside a tube and let it bob freely. The buoy will be slightly smaller than the tube so it will not have much room to swing to the sides. If I use a viscous non-toxic oil, it may reduce clattering while providing constant lubrication. A magnet will fasten to a rod coming out the top of the buoy. The top of the rod will pass through a hole at the top which will keep the rod aligned. The magnet will have to turn the buoy and rod, but I could decouple them.
I may forego the rod and place the magnet inside the buoy for simplicity. Either way, the bottom of the buoy will have to have a hole during printing so I can clear the resin before curing.
