Living Hinge Earring

After seeing some laser cut living hinge earrings, I thought it would be fun to do 3D printed versions. I came out with a variety of designs and even tried layering some to make them multi colored. I used Tinkercad to make these and also have a tutorial on Instructables where I go into more detail about designing and printing them.Instructables: https://www.instructables.com/id/Living-Hinge-Earrings/Tinkercad: https://www.tinkercad.com/things/1GWQ0EntjiY After testing, I came up with 7 variations I liked though there are of course many ways to do these. I found the variations where the design cuts almost all the way through each way was most flexible. The ones with cutouts in the middle aren't as flexible, but still bend enough for earrings. I recommend you print single color (or two color if you change color halfway through) designs at about 1.2mm or 6 layers. This seems to give you the best combination of flexibility and stability. For some of the designs, I did print them up to 1/8"
