You can adapt freecad model to your borescope camera if it does not fit. I use this 5.5mm diameter borescope camera:

With 5.5mm diameter and top of borescope holder, bottom of camera is 7mm below extruder carriage, still 1mm above nozzle. Becing above nozzle is important to avoid collisions.

Cover photo shows fixation of borescope holder with superglue, 2nd photo shows 640x480 snapshot taken from OctoPrint. Borescope camera is used as part of “OctoPi and Pi camera holder” model:
