A little thing to mount an Arduino Uno and breadboard together for (slightly) more organized prototyping.-Print part. I printed raftless using SF35 MK7 Print-O-Matic defaults. -Find yourself three M3x12 bolts and three M3 nuts(designed for square but a hex will probably squish in there). Bolt the Arduino to the mount as shown. -Snap in your breadboard of choice, and prototype something awesome.
