First; a video of the end result.

I gathered supplies:

Then sanded the frame.

Then drilled out the holes for the arms:

Then traced out the lenses:

I determined the correct interaction angles. (Secret sauce)

And then cut out the polarizing film first, in the future this should really get either stamped or lasercut out. At the very least I should print out the lens guide.

I checked the fit of the polarized film.

Then I cut out the mica using the same template. The particular sample I was using was rather thick so I had to make relief cuts and there was some delamination.

Then check combined fitment; the frame was a little springy so I had to relieve pressure before laminating. Note that the lens pockets are half blind and not deep enough at the time of this design, works for now though.

Lined up.

Clean and assemble.

Applying glue and weighting into place.

I measured and then starting bending the wire to shape of the arms.

While I was trying to fit the arms I ended up tearing out the pivots, so I just ended up wrapping the wire and doubling back to make a joint. It doesn't really flex so no folding.

And for some not so great selfies: (my remote was acting weird, probably low battery)

I'll get additional photos later.
