My Twin Wide Angle Lens Adapter arrived ... just in time for my walking trip in the Fiordlands National Park in New Zealand: Here it is, with machined brass thread inserts fitted. Here the lenses have been screwed in. Here, fitted up to the Twin Rig ( http://www.shapeways.com/model/72937/baseplate_for_stereo_3_ d_twin_rig_camera.html) and ready. Here, with the twin lens cover ( http://www.shapeways.com/model/93536/twin_wide_angle_lens_ca p.html). Here, with the win back-cap fitted ( http://www.shapeways.com/model/72950/twin_rear_lens_cover.ht ml), for dust-free storage when not in use.
