Summary

A cover for the camera on Google Glass which can be easily flipped up or down.

Instructions

This was just a quick proof-of-concept made of polycaprolactone, the thermoplastic known as ShapeLock, InstaMorph, et al.

First, get a piece of a thin wire paperclip about an inch long, and bend it in half. Now unbend it. Unbending it will not result in a perfectly straight wire, but will result in a kink which will be useful later.

Next, get a glob of PCL softened in hot water. Take it out (carefully!) and shape it on the edge of a box, desk, or other surface, into an L shape. Each leg of the L is about 1/2 x 1/2 inch, and 1/8 inch thick.

Stick the wire through the bottom edge of one side of the L so that the kink in the wire is about halfway through. Let the thing harden.

Next, bend the wire next to the PCL down, and then about 1/8 inch below that, bend it horizontal again. You just made a raised hinge.

Get some JB Weld and glue the hinge to Glass so that the L-shaped piece of plastic can cover the camera in the down position, and reveal it in the up position. That kink in the wire will help to keep the plastic in its up/down position.

Finally, paint the plastic. I painted it black to match the frames, with a red X for the down position and a golden eye showing in the up position.
