These cones roll UPHILL! See https://youtu.be/da5RdDmNDv4
What is the explanation? It is a physics lesson about the CoG (Center of Gravity).
Each part is in two pieces which will print on a 6" x 6" print bed. Print two copies of the cone and cylinder and join them with glue, or my preferred method is to touch them with a low heat soldering iron.
There is no trick to using them. The white cylinder naturally rolls downhill and the joined cones naturally roll uphill without a push. No weights, magnets or strings are used.
