The Case:

To make it easier for you to assemble those parts we made a 3D printable case.

The Plans are here.

If you don’t have a 3D printer, that’s fine, we don’t either! We used 3D Hubs services to print our version (it was fast and the price made sense). The price will depend on the material you use. It cost us 95EUR (100$) to print at our hub in Paris.
