This thing was made with Tinkercad.
Protect your nanotech camera, make a paramedic jump kit for a mouse, wear it on a chain like a modern locket. There are many images, make sure you scroll both ways.
The print photographed is Shapeways' "Black, Strong and Flexible"
There is no tolerance in the hinge joint of this two-piece Thing. The hinge is designed with perfect precision. In preliminary prints, the hinge works very well, but is obviously fragile. This could be beefed up, but would spoil the scale of the miniature. Open to thoughtful feedback.
