Raspberry Pi breadboard tray
Was tired of bread board moving around or falling when I moved a wires so made this in SketchUp. Works well for my purposes, thought others might find it useful. This is my first real custom design. Handle is entirely optional. Mostly just to see if i could do it, or if your setup was very delicate and you wanted an easy way to lift it.
Update: Put up a new revised STL that makes the B+ fit better. Before it was at a wonky angle
