VR Goggles Face Interface

Hi CADers!
I am modelling in Rhino some custom VR goggles I am wanting to build, and was wondering if anyone had solved the challenges of the ergonomics of fitting Goggles to various face types? Is there a repository of the 'average' head in .3dm? Have been doing research but wanted to reach out to the community to see what other users have been up to!
best regards
