Mechatronics robot parts

My students build robots for the mechatronics class I teach. These are parts I used for mine. Stand to lift breadboard off the base of the chassis. Mast to hold the GPS/compass away from the motors' magnetic fields. Sail because I teach at a maritime academy and it's nautical. I printed a little pirate for a captain using this design: http://www.thingiverse.com/thing:144775
