Using the lens explorer I made a frame which has integrated hinges, snap in lens tolerances, one degree sweep suitable for casting or rapid prototyping.

Since the lenses are flat I went for a straight sweep.

The lens templates and original hinge can be seen here. The hinge seemed much too small, I figure with a one millimeter wire the spring moment arm should be larger.

Connecting the pivots to the frame was tricky, and its still not quite right. Surfaces could use to be blended differently. There is no nose bridge right now since I haven't decided how I want to move forward with that. On one end I could just buy wire and gummy ones, or adhesive pads which go on the fin types... But then I have very little control, and I can't reliably get them local. I can't just say "screw nose support" because.... metal is cold usually and it would just be lazy. So I gotta figure that out. Hopefully this model helps make that decision.

Overall, looks pretty decent to me. Nice and simple, for now.

Using an old stash of my Grey Pro 2 for the Form 2 printer... Ahem anyways i'm hopefully going to have a plastic frame on Thursday, going out of town tomorrow.
