Magnetic levitation module base

I made a base for the OEM magnetic levitation module you can order [here](http://bit.ly/2HNM5fu). In addition to the module, you'll need:

* 4 M3 x 0.5 mm, 16 mm socket head screws such as [these](https://www.mcmaster.com/91290a120)

* 4 M3 x 0.5 mm hex nuts such as [these](https://www.mcmaster.com/90592a085)

And you'll also need clear plastic for the windows cut to 10 mm x 26 mm. I walked around Target looking for clear plastic packaging, found one with 3 scented markers in it, gave the markers to my daughter, and cut up the packaging :)
