Screw that ebay seller. Profiting from things posted for free on Thingverse is taking the p!ss, not to mention illegal. I get that they're providing a service for people who can't print their own, but it's still not on.
For what it's worth, I printed that one myself and wasn't all that impressed. While the top was definitely closer, from what I could tell the bottom was almost identical. The claim of your eyes being 15mm closer to the lenses seemed an exaggeration at best.
I downloaded the CAD file (

I wear either glasses or contacts, and while the stock one is fine with my glasses the modded one is closer enough to push them uncomfortably against the bridge of my nose. Great to have the option of contacts and wider FoV for longer sessions, but to easily swap face plates for use with glasses if necessary.
Considered sticking the nose piece from the Vive to it as well, however for DCS and FS I'm finding the gap pretty useful to peek through.
