Rail'n'Motor - with support, cable channel and diode holder.

Description
Support parts added for the motor traversing the circular rail. Mini ball bearings for 'wheels' and a cable channel added on the side with the purpose of both keeping the motor from slacking behind and supplying current (copper rails on the inside of the support wall). Individual parts will be printed in ABS plastic, using a Thing-O-Matic. The rail will carry a small 632nm diode and for that, a holder has now been added.
