This is a protective casing meant for an Arduino UNO R3. It has pin accessibility through a plexi top. It does a great job protecting the arduino from static shortages and just wear and tear from everyday use. The box is currently being used in my school's robotic class to protect an arduino. It is is nicknamed, "The Shaanduino". I am just going to post the files instead of a step-by-step instructable to make it easy for you guys.
So the top part is see through so you can see what is going on in the arduino. It has easy acces to all of the input and output ports. i am attaching 2 files of the same thing. 1 is a .STL and the other is .SLDPRT. I cut my part on a cnc laser blaster. You have to export the file and you may have to convert the file to a different format to print on a laser cutter.
