Replacement lensholder for durovis opendive

I got tired of the lenses moving around so I designed this replacement lens holder for the durovis opendive. It's also part of my remake at http://www.thingiverse.com/thing:363203
It's for the 25mm diameter lenses of the durovis lens kit.

Uploaded a variant with 65mm interpupil distance. (Not printed by me)
