This is a 3D-printed desktop traffic light status indicator.

• Appearance Fidelity Its exterior perfectly replicates a miniature upright traffic signal, featuring a black housing, red/yellow/green lens assemblies running from top to bottom, and even the shading visors on the lenses—delivering exceptional accuracy. The piece exudes a retro, industrial aesthetic. As evident from the layer lines, this is a quintessential FDM 3D-printed object: the outer shell is printed in black PLA/ABS, while the three lens assemblies are crafted from translucent red, yellow, and green filaments, respectively.

• Core Function: Desktop Status Indicator Beyond being a decorative item, it also serves as a practical status light:

  • Red Light On: Indicates “Do Not Disturb / In Focus / Busy,” such as during meetings, live streams, or coding sessions. When the red light is on, others know not to interrupt you.

  • Yellow Light On: Signals “Wait a Moment / Almost Ready / Briefly Away,” for instance when handling an urgent task and expecting to return shortly.

  • Green Light On: Means “Available / Welcome to Disturb / Open to Communication,” signaling that you’re free and receptive to interaction. This intuitive “signal language” makes it ideal for placing at your workstation, allowing colleagues or family members to instantly understand your current state without words—perfect for remote work, students, or any situation requiring focused concentration.

The assembly process is remarkably straightforward.
