Cardboard VR goggle for 5.5' phone

I just don't find no 3d printed VR goggles that satisfies me, so I drew my own.

The lens holder is for 50mm lens, I might upload different sizes when I have time.

but you can always customize yourself with the provided FreeCAD file.

I suddently found that the front is too heavy and keeps slip down, and I happened to look for some weight to put on the back so it becames more balanced.
A broken 2.5' hdd just came into my sight... It even have it's own screw holes!
