Post-Printing

Assembly requires six #6 x 3/4" (or metric equivalent) countersink head sheet metal screws. If bed heat fails to prevent warping of the base it is tall enough to allow the bottom to be sanded flat afterwards. Some foam, preferably self-adhesive, can be attached to the inside of the cover to secure the marbles for transport.

How I Designed This

This was entirely designed in Autodesk Fusion 360. Take a look at the following video to see how mechanical linkages can be tested and animated under simulation.
