This is a design for a DIY Tally Light box for visual indication of multi-camera queuing to talent.
This design is meant to enclose the 7 RGB LEDs (WS2812B-3535) shield onto a mini WiFi board based ESP32-S2FN4R2 for Wi-Fi IOT.
Assembled, these two-boards fit into the Tally light container that accommodates access to the USB C power/programming interface, and the ESP32-S2FN4R2 reset buttons.

Programming for one or more Tally light boxes can be found at the following link.

The container can be printed without supports. However, the Top will need supports. A Brim is advised for both prints.

A single 3mm x 4mm screw is used to secure the top to the container. An appropriate hole should be drilled in the correction position using the guide hole in the top piece.

A third print option is available for printing with a non-translucent filament. The H version container has an open front that can be sealed with a piece of white paper (preferably from the inside as an insert) or left open. A non-translucent top will still allow light to be reflected to a camera operator through a rear facing hole. The amount of light moving to the rear can be increased by inserting an opaque surface in front of the LEDs such as a piece of whit paper.

Temperature differential of a sealed unit is tested to be < +3 °C between inside and outside with an exterior ambient temperature of 22 °C after 1 hour of continuous operation.
