Raspberry Pi Model B Stand

A base to mount a Raspberry Pi microcontroller on, to reduce the chance of contact of the board with liquids, dust, or metal, and so that the board can be handled more easily.
Allows mounting on clamshell laptop using ClamShelf.
Design based on Model B revision 2 (2012).

This stand has beveled sides that slide into the ClamShelf; vents in the beveled sides to allow circulation under the circuit board horizontally, as well as vertically through the open top and bottom; guides to help position the circuit board; and screw holes in the corners so that several stands can be stacked using #4-40 screws, spacers, and nuts.
