ESP32-CAM Focus Adjustment Helper

This is a handy jig to hold the OV2640 camera of an ESP32-CAM in place while you adjust the focus with an adjustment tool. This prevents the camera twisting on the delicate ribbon cable or risking a sudden wrench if the lens is already glued on and breaks away.
It simply sits over the lens assembly and fits snugly over the sides of the ESP32 board.

I've put a small bevel on the cut-out to reduce the effect of first layer spread causing the hole to be too tight on the lens body, but go careful when you first use this device to ensure you don't drag the OV2640 off when you remove it.
