<ul><li>This is a miniature replica of the Berlon clock "<i>Mengenlehreuhr</i>" designed by <strong>Dieter Binninger</strong>.</li><li>It's a Clock that works on the mathematical principle of set theory.</li><li>The working principle is simple :<br/>• There are 24 light signals arranged on 5 levels.<br/>• The round box at the top shows the seconds (by flashing once every second).<br/>• The first led raw contains 4 led and each box represent 5 Hours.<br/>• The 4 boxes below each represent 1 hour.<br/>• The third row contains 11 boxes which represent each 5 minutes. (note that the third, sixth and ninth led of this row are red to represent three quarters of an hour more easily).<br/>• The 4 boxes in the last row each indicate 1 minute.<br/>• The clock reads top to bottom.</li></ul><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Prusa</p><p><strong>Printer: </strong></p><p>I3 MK3S</p><p><strong>Rafts:</strong></p><p>Doesn't Matter</p><p><strong>Supports: </strong></p><p>No</p><p><strong>Resolution:</strong></p><p>200</p><p><strong>Infill: </strong></p><p>20<br/><strong>Filament:</strong><br/>[Prusament PLA ](http://www.amazon.com/s?url=search-alias&amp;field-keywords=Prusament+PLA&amp;tag=thingiverse09-20) </p><p><strong>How I Designed This</strong></p><p> </p><figure class="image"><img src="https://cdn.thingiverse.com/assets/be/0b/cc/7a/ed/Mengenlehreuhr.png"/></figure><figure class="image"><img src="https://cdn.thingiverse.com/assets/fa/81/d8/e5/9e/Mengenlehreuhr\_Image.jpg"/></figure><p><strong>Global structure</strong></p><p>• This project was entirely designed and modeled with Tinkercad.<br/>• The model has also been modelized in order that the front face is on the heatbed.</p><p>By printing with a Prusa i3 Mk3s+ (or earlier) with a textured PEI Powder-coated Steel Sheet, it is possible to get a "mat" effect.</p><p>Category: 3D Printing</p>
