Team #4905 (Andromeda One) was taking inventory this year and noticed we have a lot of Denso Throttle Motors and thought it would be nice if we could use them somehow. Not finding any readily available gearboxes we decided to try and design one that we could 3D print as an off season activity. What started out mostly as a lark, turned into something that could actually be useful. The printed PLA gears and gearbox seem to be plenty strong for the limited power of the Denso motor.
After discussing this with the team we decided to publish the design and open it up for all teams to use in hopes that some of the Denso motors could be used for more than just paper weights. If you decide to print one please let me know your experience. If other teams find this useful We will endeavor to improve it. The files for 3D printing can be downloaded at:

In the end engineering is what happens between your ears, not what you build with your hands, not what a machine spits out.
