I designed an outer casing for the ESP32-CAM (attached to the USB programmer). I built it for personal use but hope it is useful for you too. The back part is removable, making it easy to open whenever needed. The casing has holes for two switches and the USB port, allowing you to upload code easily. The image shown is printed in PETG Grey, but you can use any other filament of your choice.

Steps:

• Print the two models provided.
• Place the ESP32-CAM and the programmer into the top shell, and secure the programmer with double-sided tape on its back. (See the image for better understanding)
• Attach the back shell to the top shell. This design ensures that the ESP32-CAM and the programmer are securely held in place. You can open the back shell when needed, and it will remain attached to the ESP32-CAM.
