Lens Holders scaled for 30mm 7x lenses and scaled up opendive model for larger heads

I wanted real glass lenses, so I bought a magnifier on ebay for about 5 dollars with 2 7x lenses. the lenses were larger than the opendive models so I modified it to use my larger lenses. I also have a big head, so I scaled the opendive HMD to be about 1/2 "wider. All other things left the same.
