I have successfully done this mod a coupe of weeks ago mainly for ED.. and all I can say is WOW its so nice to play with nearly ZERO god rays/concentric rings, text is pin sharp over 85% of the screen now and elite looks so crisp its amazing tbh its feels a lot like my DK2 with better res and FOV did back in the day yes the distortion is back but once you get it settled on your face right with the fix its near enough gone any vive users I strongly suggest having a look at the video (at your own risk ofc).
this is the distortion fix that worked best for me and i think has the best 3d Depth

and my post with tips i left on SweVivers excellent Guide
"I've done this mod myself and overall I'm very happy my vive feels like a higher res DK2 now, btw on the dust issue I got zero dust in the HMD by filling my bathroom with steam for 15 mins by running your shower/bath, then let the steam clear and do the lens transfer in the bathroom (I used a metal spudger and a suction cup and they popped right out) now you will have maybe a 5 min window when there's virtually no dust in the air oh and print the adaptors with ABS not PLA as PLA flakes. I see the same FOV with a 6mm pad and by going -2mm on your IPD removes any eye strain"
