I created a box for my IOIO. The box provides space for a 9V battery below the board. I have my battery connected with an inline switch, so I have also added an inset openning in the box for this switch (RadioShack part# 275-0409).This is an STL file that will print both the box and the lid. The lid is sized to slide right into the top of the box. Be careful the first time so you do not damage the box.The lid has been personalized with my company name. I am happy to provide the Sketchup file for those who want to change the name on the cover. I will also try to provide an update that says IOIO on the lid.
