Dahau Camera Mount

Camera Wall Mount 3 has a dome top and I printed it using a Brim in Cura, and added supports. I also set infill at 90% at each screw hole location. All other areas I used 10% infill.
This design does not need machine screws, you would use the self tapping screws that come with the cameras.

I took the original and added reinforcement to back for wall mounting, put arches in allowing better printing without supports, and filled in gaps keeping mud wasps out.

Infill should be 60% or better to allow good strength!
I printed using PETG

Version 2 Only: I use 3 Stainless M4 machine screws, and use a small o-ring on the threaded part sticking up through the top to allow for waterproofing. You could use silicone if you don't have any rings.
