Added a shelf that makes handling an Arduino + Sparkfun Joystick Shield a bit nicer.
-Increase "shelf" height to provide support to the joystick
-Increase the wall height to provide support to the joystick
-Add some cutouts or other places to route wires
The exported STL has a "tol" value of 1 mm, which is a relatively loose fit. Decrease this if you would like it to "snap in"
Print and put in your Arduino/Joystick pair.
