This is my version of the 5" FPV goggles. I used this monitor off Amazon http://www.amazon.co.uk/gp/product/B00EJG7MMU?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00 All three body parts are printed separately and then glued together with CA. The Lens is a 3x magnification fresnel lens, also on Amazon: http://www.amazon.co.uk/gp/product/B00HHQ0BS6?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00 Cut the lens to size and then glue it with CA into the lens holder. The lens holder distance to the eye can be adjusted with a m3/m4 bolt. I used Uvex ski goggles I had lying around and since everybody uses something else, just use the goggle part and cut it with a dremel to fit your goggles. Then attach that with hot glue to the frame.
