so one of the many challenges is to get the Gear VR goggle casing to fit into the helmet opening and still align on a humans face. Me being that human. I took the helmet completely apart to see what I could ditch. I removed the drop down tinted visor as that will no longer be needed. It took several adjustments, but after careful trimming the Gear VR case will fit into this area. Next I need to extend the body at least an inch to accommodate a outside cover , the hud parts and the screen parts as well.
