This is a gear box assembly that I made for light seeking robobts that my students build every year.


First, print the plastic pieces then cut two 1/8th in. steal rods for axels and add a small hobby motor. I bought my motors from a cool website www.Kelvin.com (Part #850646 Price: $0.85)
I also just bought the worm gears and spur gears from Kelvin, but I thought it might be nice to just print your own. :)

If you want to order parts:
Worm part # 390621
Gears part # 990179
Wheel with gear part # 990173
