External Shape Library (Volume 2)

So now we have the good stuff. This one has:

* Arduino
* Hobbico Command Standard Servo CS-61
* 6xAA holder
* 4xAA holder
* 4-40 english unit screws and nut (these are what I use; should be easy enough to scale these to your own specs...)
* LEDs
* Standard DC Motor

The DC Motor can be had pretty cheaply:

The hobby servo's horns are not at all manifold but I decided to leave painstakingly affixing faces in between the horns and the shaft as an exercise to the reader. (You'd only need to do this if you wanted to print a servo replica anyway.)
