Oculus Rift CV1 Lens Adapter (EU Version)

This is a remix of jegstad's excellent rift lens adapter for Zenni lenses (thing 1602460). Unfortunately Zenni is in the USA and I am not. So I made a design that fits an European lens provider. In my case it is brille24.de. But you can find them all over Europe e.g. Opticien24.fr, Brillen24.nl or Opti24.sk.
I got their cheapest glasses with large and almost round lenses (modelname: Eupen) and threw away the ugly frame. The lenses are a little bit different in size compared to the Zenni lenses. Mine are slightly oval (41mm x 45mm). I changed the frame to match them. They are simply cliped-in.
Then there was another issue. My frontal bone right under the eybrows was touching the printed frame. I redesigned the frame so that is has a much more comfortable fit. Now the new frame fits my rift, my new lenses and my face!

EDIT:
I added another version. This frame matches my face perfectly and is most comfortable. Print both and try which one is best for you.
