1 Print 2 in any color you like, if you want wheels in different color (like black).

2 Glue Wheels in holes, big wheels at the back ;-)
3 Insert earring hangers in hole through digger cabin.



When I printed at the local fablab the holes for wheels were a bit to
small so I enlarged them a bit. Once I get my own printer up and running
I will experiment to come up with the ideal sizes.

Include files:
digger.scad: the design file so you can change it to your hearts content.
digger.stl: just the digger body.
wheels.stl: just the wheels so the can be easily printed in a different color.
digger_and_wheels.stl: to print digger and wheels in one go.
