Split-Flap Display
thingiverse
A single-digit split-flap display, like the displays in old train stations. Rig it up to a stepper motor and you'll have yourself a low-power retro-cool display. This Thing doesn't include any controlling electronics. Big ups to Metrix Create:Space, where this was designed and made. Instructions Cut two sides, the frame, and ten flapboards out of 3 mm flat stock.
