Perplexing Pyramid Puzzle

prusaprinters

<p>This is one of my favorite ball pyramid puzzles. It was designed in 1976 by Leonard Gordon. For many years, <a href="http://www.gamepuzzles.com/">Kadon Enterprises</a> sold this puzzle made from injection molded clear polystyrene (see the photos). These puzzles are no longer available but you can read about their history <a href="http://www.gamepuzzles.com/pyr-mem.htm">here</a>, and you may find them for sale in places like eBay.</p> <p>You may find the same puzzle under many different names now. <a href="https://www.puzzlemaster.ca/">Puzzlemaster</a> has a metal version they call "Kugelpyramide". It is one of the most difficult 20-ball tetrahedron puzzles.</p> <p>Two pyramids can be built from these pieces. The tetrahedron with a triangular base (hard) and the pyramid with the 4x3 rectangular base (medium). The double-sided base plate allows you to make both pyramids, but need supports. The single-sided base plate includes only the triangular base.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>I3 MK3S</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>0.15 mm</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>15%</p></div> <p><strong>Filament:</strong> Hatchback PLA <br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>Print two copies of each piece (half of the piece), with the exception of "L4", which has two mirror image halves. The pieces do not need supports.</p> The pieces contain holes to aid alignment during assembly. Cut pieces of scrap 1.75 mm filament into segments about 6mm long. Stick one segment into each hole. Put a tiny amount of superglue between the pieces, and carefully mate the two halves together. <p>Print one of the base plates to build the pyramids on. You can choose the double-sided base plate, which requires supports, and the one sided base plate, which does not require supports. See the photos.</p> </div></p></p></p> Category: Puzzles
