Eyeris: Bionic Goggles

Step 2: Size The Frame

All goggles need a frame to give them shape.  We'll let the aperture that you chose determine the rim size.  In that case, measure the diameter of your aperture and make a ring with an inner diameter equal to that out of some 1/16" steel wire.  The easiest way to do this is to wrap your wire twice around the pipe with an OD equal to that of your aperture. Then cut the two loops in one place, such that you're left with a cut ring.

When it comes to completing the ring, I used a bandsaw blade spot welder, but you should be able to use super glue just as well.
