Stoplight - US Road Traffic Controls

This is a stoplight. Friction fit, no need for adhesive. Also prints without supports (although supports may be useful depending on your printer if you're having trouble with the light shroud receptacles) It can easily be modified to be a yellow casing, although if you go with yellow outside casing it would require using some other color of yellow for the light part. I've also experimented with black for the “unlit” lights.
