Simple, easily printable, and working Tippy Top. A top that spins down, pops onto the stem and spins upside down. Great for physics demonstrations and discussions. When printing, the recommended settings are .2mm layer height and 100% infill (solid piece). Also, if you are printing without a heated board a brim should be used to keep the build on the platform. A little sanding is required to round out the top of the body piece.
