This adds a top strap to the HDZero goggles. I used 3M double sided tape to hold it on and a DJI V2 goggle head strap. You can also add a single velcro strap to the stock hdzero fat head strap.

I also designed another variation to replace the plastic face plate where the foam velcros to. I did this to get my eye closer to the lens by adding velcro to the face area of this top strap mount. The file marked with '2' is the top strap + face plate mod. I'm still working on the bottom half of this mod, so if you make your own please share it here as a remix :)
