I went to 3dhubs.com and selected one of the 3d printing services nearby
Collecting it myself cost me approx 7 Euro for the mcGateway and two modules. The mcGateway enclosure is, as already mentioned by "It is quite tight fit". But since I'm not a 3d-designer I use it as it is now. The enclosures for the modules are fine (not waterproof though).
so if any-one else is willing to design some state of the art enclosures (for all the hardware, including the dongle and if possible waterproof) than that would be interesting to see. And sharing the 3d print files to use would even better
Of course we are also still waiting to receive the enclosures form mcThings (Kickstarter)!
