3D Printed Gearbox for Denso Throttle Motor Available

[AndromedaOne]

Ari423 - I like the idea of using adding a second motor, I'll definitely do that.

Pilleya - The gearbox is designed with 10:1 and 18:1 gear ratios and is designed to drive 1/2" Thunderhex shaft. It could easily be modified for 1/2" hex. We use a lot of Thunderhex so I designed the gears to fit that. Total weight is less than one pound. I'll look into adding a lower gear ratio, but that will probably be a new gearbox with a single gear off the main motor. Probably even more useful in this case to add the second motor option.

WIG1350 - The design does include grooves for the gearbox plate, but they are not deep and the motor does ride proud. I agree that bosses would be nice but including them would have required support material for most of the gearbox face. Recessing the motor would make the gearbox thicker by that amount. I do agree with you that the motor mount design is not optimal. What might work is printing a standoff plate that would mount on the engine before mounting to the gearbox. That would actually allow me to thin the whole gearbox down a little.

Thanks for the positive feedback everyone. I'll look into these improvements as time allows.
