I knew my rust bucket Prusa Mendel would come in handy one day. I take advantage of its mediocre print quality by making lots of “jam fit” designs. Stuff just snaps together.

A trifecta of dorkiness: I’m making custom lenses with a 3D printer for the Oculus Rift, in order to better play Minecraft. Because of my myopia (short-sightnedness), I have to use the Rift’s “C cup” lenses, which reduce field of view and corner sharpness. And in fact, my myopia is so bad, the C cups, which supposedly focus to 0.3 meters, are still too “strong” for me.
I ordered a bunch of experimental-grade (read: used) lenses from Anchor Optics. Just from mixing & matching, I found the most success with a dual lens arrangement. The FoV is wider, the image is sharp corner-to-corner, and the focal length & distance is tuned to my particular myopic eyeballs. The significant downsides are: The Rift is way heavier on my face due to 2x glass elements per eye (as opposed to single-piece plastic lenses), the lenses themselves are a lot larger & taller, making me turn the screen distance controls on the Rift body as far as they can go, and the distortion is a tiny bit different (the resulting image on Rift demos is a little pincushioned).
I have more lenses in the mail, and I hope to end up with something much shorter.
If you want to mess around with lenses yourself, check this out http://vrwiki.wikispaces.com/Oculus+Rift+mods … The other important bit of information is I think someone said the standard Oculus Rift lenses have a “focal length” of 45mm --i.e. “infinity” becomes 45mm when you look through them, and that’s why the Rift focuses “to infinity” with the A-cups mounted 45mm or so away from the screen.
