A simple platform on which to mount an Arduino Uno and a Radio Shack perf board (RS P/N 276-158, though others probably share the hole spacings). I milled it from 3/4" particle board with a ShopBot CNC router. Feel free to request cut files if you'd like to do the same.

Just the board outline, mount hole locations, and clearance massing underneath for soldered protrusions. I made it to go into a simple platform mount, so the topside components weren't important for the model. At some point I'll update this... if someone else doesn't do so first!
