Bionic Bookshelf Mount

prusaprinters

<p>I was testing a new topology optimization software, and having issues with a real life part, decided to try the simplest thing I could think of: A shelf mount. This part is optimized for maximum load with minimal material use. The screenshot shows the part under a 50 kg (110 lbs) load (!), with material stress staying under 20 MPa.<br/> In addition, the part is designed to print completely without supports. Print time around 5 hours on my Prusa i3 MK3s.</p> <h3>Print instructions</h3><h3>Category: Organization Print Settings</h3> <p><strong>Printer Brand:</strong> Prusa</p> <p><strong>Printer:</strong> I3 MK3S</p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> 0.2mm</p> <p><strong>Infill:</strong> 100%</p> <p><strong>Filament:</strong> Doesn't matter ABS or PETG<br/> <strong>Notes:</strong></p> <p>It will probably also be fine with 30% infill, however in that case the permanent compression under the screw head might cause long term problems. 100% infill doesn't add a lot of material, since most of the part is already very thin. Print with at least 2 shells, 3 is better.</p> <h3> How I Designed This</h3> <p>CAD work with SolidWorks 2017, topology optimization with ANSYS Discovery Live Beta.</p>
