Nexus S phone holder

This thing will hold a Google Nexus S phone reasonably securely, exposing the camera in the back (not the LED).
I made this to attach the phone to a telescope and/or microscope via interchangeable attachments. I printed it on a Rostock Delta in PLA (with supports for the corner pieces), it fits the phone snuggly. It is not a full case, but could easily be extended to one - it might be a little bulky in its current form.
