Thank you to Sneaks for an amazingly designed project. I ordered the wrong camera by mistake and I wanted to make it work instead of returning it. The front cover prints with no supports and no issue whatsoever. I used a brim and supports for the bottom piece, it was printed at the high speed of an MK4IS though, so slowing down the print may eliminate the need for it.
The author remixed this model.
Moved the pins inside camera housing front and back to line up with an IMX708 12MP Wide Angle Camera, increased hole size for the lens, made flange heights taller, and made the snap-in connection a bit deeper so the cover can't slip off.
