This model is an exemplar of many different 3D prining concepts.
- When the model is well designed, you can print a multi-part articulated item all-at-once with even an inexpensive 3D printer.
- The concepts of open source and iterative design allow one person to come up with a good idea and others to build on it and create even better versions.

And it’s a lot of fun to play with.
