3D projection of 120-cell

prusaprinters

<p>Here is a model I constructed of a 3D projection of a 4D shape called the 120-cell among other names. Learn more about it here: <a href="https://en.wikipedia.org/wiki/120-cell">https://en.wikipedia.org/wiki/120-cell</a></p> <p>Also check out some videos on Youtube. Search Youtube for "120 cell" and see if you can understand how this is a 3D projection of that 4D object... Good luck!</p> <p>I'm still learning how to use the tools to generate better and more printable stl files but if you do print this, use a wide brim at a minimum and scale it up as needed or run it through a tool like Blender to thicken it. You may need additional support also depending on your bed adhesion (I used an 86% overhang angle touching the bedplate only). You will most likely want to scale the smaller model up by 200% or 300% or more in the slicer because it is very thin at the current scale (too thin really to be successful with a 0.4mm nozzle). The inside of the struts may be hollow so I'm still thinking about how to solve that issue to make them solid. I will likely be replacing these stl files as I figure out how to improve them.</p> <p>Have fun!</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 5</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>.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>100%</p></div> <p><strong>Filament:</strong> eSun PLA+ PLA+</p> </p></p></p> Category: Math
