thingiverse
This was designed as a tiny hinge to connect two pieces of styrofoam or thick padded poster-board. Basically, print a few, stick a pin through the hole, and you have a hinge. (Bend and snip the pin ends to complete.) Stick the barbed ends of a couple of these into two pieces of styrofoam to connect them together with a bendable joint.. (It is recommended that you put the build-plate sides of the hinges facing each other so they slide more smoothly.
Many parameters are settable to adjust it to your needs.
You can also customize this in Thingiverse's Customizer.
