This is a case for the serial (I2C) LCD module from Digistump. It uses the I2C shield mounted on the digispark board. I have included the openscad file so you can modify it. The design has 2 cases. A flat case and one which I like more under an angle. I also included a bottom part which I don't use. My digispark case can be found at http://www.thingiverse.com/thing:41291
