Hey, this Model is another collaboration by Keishiro Ueki and me Ruven Bals. Keishiro invented the mechanism and I made the 3D model and the Guides. It's a Variation of the Jitterbug. That's also used in my Expander.

Take a look at Keishiro's Work on his maker world profile.

You Need: 8 Triangles 12 Connectors The tool is optional. You can also use glue instead of using the printed Connectors.

Print Settings: Standard for your Filament. No Supports.

Assembly: I made a PDF Guide that's included in the download as well as a Video Guide.

Troubleshooting: If the Connectors break, just use glue to connect the Triangles. If the hinges don't work smoothly, try using a smaller layer height or the "fine" profile in your Slicer
