3D Printed STEM Robot

This is a robot chassis based off the Science Channel video showing a father and daughter making a similar robot with wooden sticks, hot glue and tape. The concept behind this is to allow for easy making of the chassis and legs in a classroom setting. I have also included the Fusion 360 source file so you can modify things.
Item recommendations:
3-6V DC geared motor (make sure it has dual shafts)
3V AAA battery holder, helps if it has a switch but not required
Here is a short video on the printing and assembly of the parts.
