Echine FPV Focal Extender

thingiverse

I bought budget FPV goggles (Echine EV800) that had a major problem with focal distance for someone with excellent eyesight like me. Since I don't wear glasses and have perfect vision, I was puzzled about why focusing on the display was a challenge with these goggles, especially since there's no way to adjust focus on this model. But after separating the two sections of the goggles, I found that I could see very clearly when they were apart by about 2-3 finger widths. So, I came up with a simple design for a spacer that adds around 1.5 inches, allowing me to focus without any eye strain and not affecting my field of view at all.
