Pentadodakagon Puzzle with Calculator This is my contribution to the Make Anything Design Challenge. The Idea: This puzzle is based on the well-known pentomino puzzle - transported to the 3rd dimension. It's modular - you can start by printing a few parts (without support) to get a solvable puzzle. Whenever you need to test new filament, have to deplete the rest from a spool, spent a rainy day inside, or want to drive a friend crazy, you can print additional parts to make the puzzle more complex - or easier to solve. Check out the calculator, just click the "run" button to find solutions. Getting Started: To get a simple puzzle with a height of two rings, you need only 6 parts. 4 'pentos' and 2 'rings'. E.g., print pentos: I, L, U, Y; rings: 1, 3 (and optional: base, pin2). While trying to solve this puzzle, you can print the base plate (base) and the center pin for two rings (pin2). Printing: - 'pentos' and 'rings': 2 outlines, 3 bottom/top layers, 20% infill - 'base' and 'pins': 3 outlines, 4 bottom/top layers, 33% infill Chamfers are designed for 0.2 layer height (Hint: if the pin is too loose or does not fit in the base just scale up/down X and Y of the pin). Add Complexity to Your Puzzle: Just print a new center pin, two additional pentos, and another ring. (Hint: To make sure the puzzle is solvable with the new parts use the calculator.) Reduce Complexity from Your Puzzle: Just print other 'pentos' or 'rings'. (Hint: Use the calculator to make sure that the number of solutions increases.) The Calculator: I wrote a calculator to solve a puzzle with given parts or generate a solvable puzzle within given parameters. You can also use it as a tool to check the complexity of your puzzle - just take a look at the amount of all found solutions. It's written in plain JavaScript in a single HTML file. You can use the calculator online or download it to use it locally. (Hint: The code is far from perfect.) Design: I designed all parts in Fusion360, learned a lot!
