In design school I made a robotic dog, Gizmo, aimed at teaching children body language of dogs for safety reasons. Since getting an Ultimaker 2, I couldn’t resist the idea of printing a physical copy of my old project.
I eventually took it to the next level and designed a 3d printable file with no overhangs that snaps together. This gives the dog articulation so it can function like the original design, allowing the user to manipulate it into various positions. You can find the 3d print files here.
Here are some of the prints of Gizmo done by others in the thingiverse community:
