First upload of a modified vex gear just to test out my STL exporter. I'm going to use this gear in a small arduino-based robot called the "O-Bot" or Open Bot. Basically it is a vex 60 tooth gear that I changed so it would accept the 1/4" shaft of a stepper motor, and screw on tight with two 1/4" 20 nuts. Edit: Fixed the download so that the hole for the nut is the right size. Edit 2: changed model for easier printing without supports
