This is a custom-designed holder for the ESP32-CAM module. It features two M3 holes with a 20mm center-to-center distance at the bottom, designed to use M3*4*5 inserts. However, the design file is included in the description, allowing you to modify it to standard M3 holes if needed.
As shown in the image, there are two versions of the ESP32-CAM module: one with a thicker PCB and one with a thinner PCB. I have uploaded two separate versions of the holder to accommodate both. Choose the appropriate version based on the module you have, or feel free to modify the design to fit your specific ESP32-CAM.
