Ball Bearing Speedometer frame.
Needs two photodiodes, two LEDs (Amazon sells packs with both of these), an Arduino or similar microcontroller, two 10M resistors, and two 220 ohm resistors.
The frame should print with no supports, although I'm still working on the best way to print the track connectors.
