The chassis was designed by ArtizanWork and produced by Shapeways, a Dutch company that specializes in 3D printing.
The cases are therefore not knitted by hand, but come from the factory.
The sides are solid, while the grid at the back of the iPhone is much smoother.
The knitting serves as a shock absorber that protects your iPhone.
You can order the case directly from ArtizanWork for $75.
