Mid-Century 4-Way Traffic Light

thingiverse

###1/4 scale Mid-century 4-way hanging traffic light Designed in Fusion 360 as a practice project, this miniature traffic light is made up of multiple interconnected pieces. To assemble it, glue the parts together carefully. The "hanger" piece features a hollow tube that allows wires to be threaded through it just like on a real traffic light. This design provides a convenient way to connect the LED lights or other small sources used in the reflectors. **Important Note:** The main body piece is printed upside-down for added support, as the original design was too delicate and prone to breaking during printing. To address this issue, internal support structures were added to prevent it from snapping into pieces while being printed. On June 30th, a new version of the hanger STL file was released, correcting an error in the original order of operations that resulted in a non-hollow design. This update ensures that the wire tube is properly aligned and functional. By July 1st, all parts had been successfully printed, paving the way for the next stage of assembly: sanding and polishing the reflectors to achieve a smooth surface, followed by painting them silver and mounting LEDs and wiring. On July 29th, the project was finally completed. Instead of sanding and polishing the reflectors as initially planned, they were simply painted silver. The addition of LEDs and an Arduino Leonardo-compatible microcontroller stuffed into the top cover enabled control over the light. A cheap cell phone charger and micro-USB cable powered the setup, requiring a USB cable to be cut and re-spliced to fit through the wire tube in the hanger.
