This traffic light toy changes state through a manually rotated shutter.
The design is intended to be used with translucent filament lenses and a single internal light source, but it could easily be adapted for multiple bulbs.
Printing If oriented correctly, all parts can be printed without supports.
This design includes alternate versions for several parts. Print only what you need.
For best results, use a translucent filament when printing the lenses. Use a thinner lens if translucent filament is not available.
Customization This design was created with several possible versions in mind.
Rotating Shutter This option uses a rotating cylindrical shutter in the center of the model to let light pass through only one lens at a time.
Solid Shutter Use this if you want a play-friendly non-electronic traffic light. Just skip adding the lenses and either paint or use vinyl stickers to give each layer of the solid shutter the desired light color.
No Shutter This option drops the rotating shutter and leaves the center of the model completely open so that light will pass through all 3 lenses.
Sectioned This option divides the center of the model into separate segments. Use this option if you intend to control the street light electronically.
Hanging Use these variants if you want to hang the light on a wall.
