A quick proof of concept to show how 3d printed parts can work with Lego

This is a quick 4x4 crawler design to show how 3D printing and LEGO can mix. I used a turntable for a center pivot. The front and rear have double wishbone suspension, and there are helical gears transferring the rotational motion while gearing it down for more torque. There are sound improvements with helical gears, and I found the 3D-printed differential could take more load without deforming. The center turntable could take quite a bit of load too!
