HT1 Belt Drive Conversion

This is a direct replacement for the HT1 spur / pinion gear system. After breaking my original gears very quick I decided to make my own "Belt Driven" conversion for it. I used a quarter sized rubber band as well as the factory hardware. After printing, no sanding was required but I did use the tools that came with the HT1 to thread the gearshaft and reem the hole out for the motor shaft. If you have any questions, just ask.
