simple eyeglasses frame, intended to fit red blue foil as lens (frame is 1D curved so the foil will not wrinkle)

another idea is to print some raster with "holes"/lines/squares/etc on transparent foil and insert this as the "lens"

hinge is made from paperclip wire (1mm) from one end (1-2mm) scratched with pliers to stay in place due friction

also included old frame front version, thinner, with tighter groove, and it was difficult to print and clean
