I bought the EV200Ds and I absolutely love them, out of 5 different pairs of goggles they are the only pair that comfortably fit my big head and wide IPD.
They come with covers that go over for the front of the goggles but I really don't care for that as they are super shiny and I am not really into bling and the ones with the displays do not fit the Pro58 receivers, the Pro58 sits deep inside the ev200 and comes no where near the front of the faceplate that comes with the EV200s so I made my own.
I also made a blank one to cover the other the other bay so that the goggles look good without the super shiny face plate.
Here is the blank one.
0.1-0.15mm layer height
I used support (you can rotate it so you do not need support by laying it down but that makes the locking tabs more brittle)
infill doesn't matter.
