One of the aims of this project is to make it easy to create cases for your creations. Of course you can put them into any kind of box - one of our members has put hers into a "Connected Sandwich Box" - but it is always useful to have some nice boxes right at the start.
With that in mind we've produced a set of 3D printable designs that you can use to make boxes that are easy to print (no horrible overhangs) and easy to fit together. And we think they look quite stylish.
You can find all the design documents for our boxes at the GitHub site here. We even include designs for clamping your Wemos ESP8266 securely into the box.
