Summary

Suppose your favorite glasses are broken. Usually this is frame, temple or -most likely - the hinge. But the lenses are OK. But hey - we have our 3d-printer and enjoy 3d design and printing. Let's design and print our glassesusing the surviving lenses! OK, it's understood my print is hardly useful foryour particular lenses. Unless you wear the same Zenny Optical glassesmodel I buy online here (this is NOT ad - just technical, I hope youunderstand): https://www.zennioptical.com/p/plastic-fashion-full-rim-frame/2329?skuId=232921 So I guess this print may rather provide aninspiration, some ideas and instructions on how to design around youravailable lenses.

Start with a picture of your lens as a canvas. Calibrate it and draw a niceclosed spline following the edges of the lens precisely. Then make offsetsof the spline on both sides - internal and external. Then extrude it -internal part less and external part more - so that you get kind of a "dish"with a hollow bottom. This would be a rim around your lens with a narrowsupporting edge from the forward side of the lens. Print it now! - just thisrim. Your lens should go into the rim from behind under pressure and staythere just by friction. This is crucial for the project - the lens should firmlystay there and be possible to remove with some effort. I don't use anygroove or support from behind the lens. This makes it possible to replaceframes in a couple of minutes. My lenses are sitting just fine, never cameout. So, when the lens rim is adjusted , mirror the design for the secondeye keeping the right distance and orientation. From this point, I guess youcan use my model for hinges and temples. Just cut off my rims and attachyours. Scale it to your size and arrange to your liking. If you opt fordesigning your hinges - do them as big as possible, since we have plasticand not metal. The hinges use a piece of filament as an axis. Print theframe and the temples flat. When the glasses are assembled you will needto bend the frame and the temples a little. You can half-dip the templesinto hot water (~80C) and bend manually. The front should be bent withthe lenses in by heating very carefully around the bridge area only with aheat gun. Do not overheat. Do not dip into hot water. Do not heat theframes. Bend just slightly. Wish you good luck! Print files are probably ofno big value. Just showing I print with PET 0.4 nozzle, 0.15 layer height, 3perimeters, concentric top and bottom. UPDATE: Added Fusion 360archive, so you could better update the design for your lenses. Good luck!
