My lenses were not able to screw in far enough with the original design, so I shortened the square base to allow the lens to screw in further and lengthened the screw tube a bit as well.

I print mine using ASA filament - good for outdoors. Can withstand temp changes and UV light.

I also print mine at about 99% so the lens is a really snug fit and then I don't have to use the little locking ring.

I also use a 15' HDMI cable that I attach using a HDMI extender adapter. I also conformal coat the camera board and then encase it all in silicone.
