My frames broke so rather than spend another $300 on new frames, I decided to print a new set. This is designed to fit my particular lens shape but I suspect with creative use of the XYZ scale factors and maybe some hot air a lot more lenses could be made to work.
Use some copper wire to pin the hinges, bend into the provided slots then trim flush. May need to print the frames a few times to get the right scale factor for the lenses to snap in snug but it prints fast.
I print at 0.2mm layer height and no supports.
