I printed this off as a public demo of 3D printers in action at our local library. I also had the idea that this would be a useful tool for introducing the public to how Virtual Reality goggles create the 3D View from two seperate images. It was printed in white ABS in the makerbots and green PLA for the hinges on a Wanhao Duplicator i3 (basically a good sturdy Prusa). To reduce the internal reflections I dipped it all in some nice matt black paint I had to hand. You will notice that I entirely failed to create the mirror versions of the parts and so the screws holding the eye pieces together are on top on one side and underneath on the other side - whoops never mind!
For the mirrors I was considering getting proper first surface mirrors, but for the purposes of this experiment I decided to go for standard mirror glass. I looks for a source that was as thin as possible and came up with some 3mm thick mirror wall tiles from the local hardware shop. One tile of 300 x 300mm costing $16NZD sounded pretty good to me. I cut the 50mm square mirrors from this (is the badluck from breaking mirrors cumulative or consecutive?) and ground the edges with a rub on a sharpening stone. Because the mirrors were thinner than the space allowed I just packed it out with some cardboard behind each. In all they came up pretty well. I also found that the 3mm thick mirrors produced minimal ghosting - certainly quite acceptable for this purpose anyway.
Thanks Kongorilla for creating such a cool project. I'll probably make another 3 or 4 more to use at the VR Workshops I intend to run early next year.
