7-Color Torus

thingiverse

You may know that coloring regions on a map using four colors is possible, so that no two adjacent regions share the same color. But did you realize that on the surface of a torus, you require seven distinct colors? This shape serves as concrete evidence for the minimum number of colors needed - seven. Proving that seven colors are sufficient necessitates further investigation. Print two copies of each DoublePart and one copy of the SinglePart (using seven unique colors of filament). The pegs should also be printed. Using supports while printing helped, although I only utilize six of the pegs due to difficulties in aligning all components with precision.
