Scalable Harry Potter Glasses (with hinges)

youmagine

I found the HP glasses (Thing 94441) to be designed for tiny tots and a real hassle to wear since the hinges were prone to flapping wide open. I used OpenSCAD to bring in and enlarge the design, added stops to keep the hinges at 90 degrees and made the scale and size of the hinge pins adjustable. Use a short piece of filament for the hinge pins and you can "rivet" the ends by melting them slightly against the side of your nozzle. I've discovered that 1.25x is the ideal scale for most grown-ups and 1.15x is perfect for kids aged 8-12 years old. If you want to modify or customize the OpenSCAD file, download and save the HPV2_fixed.stl file in the same folder so it can import correctly.
