Echine FPV Focal Extender

prusaprinters

<p>I purchased budget FPV googles (Echine EV800) and the focal distance was very wrong for my very good eyes. I don't wear glasses and have no vision problems. So, I wasn't sure why I had a hard time focusing on the display with these goggles and there is no way to adjust focus on this model. However, when I separated the two sections, I found I could focus very well if the halves were separated by about 2-3 finger widths. So, I designed this spacer to add about 1.5", which allowed me to focus with no eye strain and did not affect my field of view.</p> <h3>Print instructions</h3><h3>Category: R/C Vehicles Summary</h3> <p>I purchased budget FPV googles (Echine EV800) and the focal distance was very wrong for my very good eyes.

I do suggest removing the supports from inside the slot cavity as they are difficult to remove after printing and my printer bridges that gap just fine.</p>
