This model is designed for an Esp32-Cam that has a carrier board attached (as in the picture). The cover for the case is not mandatory, you can use it without that. There is an opening for the SD card slot and the carrier board's micro USB port. The whole ESP can just be pushed into the top half of the case. I printed it with a 0.16mm layer height.

Bonus tip: I recommend you attach the camera to the SD card slot with some double-sided tape, so it doesn't wobble around.

If you have any questions, feel free to contact me.
