Square-Hexagon Hinged Dissection

This is a keychain based on the Square-Hexagon hinged dissection shown here:

The files provided are .scad files, which can be customized using Customizer and converted into .stl and .x3d files as needed. This Thing is unfinished - I attempted two different styles of hinges, but neither worked well for me. **dissection.cone-hinges.scad** is the latest stable version, but all three files are from May 2015 and I haven't revisited the project.
