Simple Rover
Simple Rover is one STL file designed by treedinstitute.com - When printed, it is a toy which uses simple machine : wheel and axle. All you need is any 3d modeling software, a software to prepare your print and a 3d printer with material of your choice.
Preparing the Model
This is the bottom part where two wheels and the connecting part are printed separately.
Preparing the Model 2
This is on the half way, where the wheels and the middle are inter connected.
Printing Position
The idea is to model three pieces which interlock so the wheels can be turned. The shape is a bit adjusted so the print goes more smoothly. As the toy is not so big, and the pieces are relatively small, I suggest slow print. It is important to position the model in the way presented on the images so it is finished from one print.
