My entry for the WyoLum Innovation Grant 2013 is my Tiny 3-Axis CNC robot.  The current version consists of 8 3D printed plastic part and 3 micro servo motors.  The parts are designed to snap-fit together with few additional parts required.  (One zip tie, a rubberband, etc)  I've been blogging about this project since November at PlotterBot com ( ).

This cheap (about $2 in plastic, $5 for each motor) robot is easy to build and easy to control with the keyboard over the Arduino serial connection using the uploaded script.

All of the parts can be downloaded from Thingiverse ( ).  All the Arduino code is on Github ( ).
