I like the original. I have been looking for something like this for sometime. I wanted a case that would enclose the enire arduino but allow to be extendable for shields. I have a particular application that uses the data logger shield that writes to an SD Card.
Render the parts you need. And export the STL's.
The code is kinda crappy. The original was measured in .001 inches. I didn't like it so I put in a scale constant to put it in millimeters. I will be adding a distance sensor, humidity sensor, and temperature sensor on the box so I am hoping to clean up the code.
Cleaned up the code. Still have the scale constant factor, I want to get rid of that.
Altered the hinge to look nicer and can be printed without support.
The SD card slot is a little tight.
