Summary The enigmatic Roman Dodecahedron remains an intriguing puzzle, with over 100 artifacts discovered but no clear evidence of their intended function. Various explanations have been proposed, yet their purpose remains a mystery. This model allows users to create a reasonably accurate replica using a hobby printer, though the interior dimensions may not be entirely accurate due to space constraints for snap pins. The through holes remain clear and precise, making it functional for tasks such as holding candlesticks or measuring distances. The model's dimensions are: Edge length: 30mm\nHeight without corner knobs: 66mm\nHeight with corner knobs: 81mm Hole sizes:\ Face 1: 26.5mm\nFace 2: 15.4mm\nFace 3: 18.3mm\nFace 4: 13.4mm\nFace 5: 10.4mm\nFace 6: 17.6mm\nFace 1-prime: Ellipse 24.2mm x 25.1mm\nFace 2-prime: 20.15mm\nFace 3-prime: 8.7mm\nFace 4-prime: 14.5mm\nFace 5-prime: 20.6mm\nFace 6-prime: 14.2mm Instructions Print one of each face (twelve total), marking each so that correct assembly is ensured. Print twenty corner pegs with three protruding prongs, which fit into five sockets at each corner. Begin by joining faces 1 and 2 together with two corner pegs. Next, connect pairs 3-4 and 5-6 as shown. Then, press pairs 1-2 and 3-4 together with four pegs. Assemble the top half by connecting face 5 to face 6 with a peg in their respective opposite corners. Line up face 2-prime with face 6 and repeat the assembly process for the bottom half. Once both halves are completed, join them together, aligning face 2-prime and face 6, then connect the remaining ten pegs into sockets. As the model can be difficult to disassemble, it's essential to verify that all pieces are in their correct positions before finalizing. This creation still leaves open what actual purpose these Roman Dodecahedron relics might have served in their historical context.
