I’ve only dabbled with cad for 3d modelling in Onshape. It seems that there all kinds of ways to add measurements in the render files. Not sure about blender.

MBD is a thing, however that doesn't really matter here, for making accessories you can more or less just assume all dimensions are perfect since you need some compliance for the accessory to be installable. What I'm talking about that can't be encoded in a model easily are things like the keepout area for the camera.

The reason you don't want Blender files at all in any sort of engineering is because it's a mesh. You can't pull any useful information, even something simple like a radius, from a mesh.
