This is a completely customizable Arduino case made with OpenScad. You can configure the height and thickness of the walls and bottom of the case.

I uploaded three versions of the case to demonstrate what can be done with the OpenScad file. You can also make your custom version of the case by editing the global variables in the OpenScad file.

UPDATE: You may want to increase the size of the arduino variables by 1mm and add 0.5mm to connectors position variables if you plan on printing with a wall thicker than 2mm.

The white print displayed here has been print with the following values in the openscad: arduino_width = 55; arduino_length = 70; arduino_usb_x = 10; arduino_power_x = 4;
