The 3D RGB Flashlight is a simple, 3D-printed project. It uses basic electronics and needs no microcontroller or coding. It has nine RGB LEDs at the front that make bright, colorful light by mixing red, green, and blue. This flashlight is more than a light source. It helps people learn about color mixing, simple circuits, and hands-on design. By wiring the LEDs with switches, the project becomes an easy way for beginners and hobbyists to explore electronics.
It features three separate rock switches for manual control. Each switch controls one color channel: red, green, or blue. Users can mix colors by turning on different switches at the same time. For example, red and green together make yellow. This direct setup is perfect for learning color theory and basic electronics. It is great for workshops, classrooms, or home projects. The rock switches are strong and easy to use. Even kids or beginners can experiment without any programming.
The flashlight uses a single 9V battery. This makes it portable and easy to power. The battery is simple to replace and gives enough voltage for all nine LEDs. The wiring is straightforward and needs no regulators or software. The body is fully 3D-printed to show how flexible additive manufacturing can be. It includes slots for LEDs, switches, and wires. This design keeps the build neat, strong, and easy to assemble. It is an accessible project for anyone wanting to try DIY electronics without complex parts.

Connection:
The diagram shows a simple circuit using nine common-cathode RGB LEDs controlled by three switches for red, green, and blue channels. A 9V battery supplies power, with resistors limiting current to each color line. Pressing a switch lights up all LEDs of that color, allowing easy mixing for different effects.
