Trefoil Knot - Version 03

prusaprinters

<p>My continuing experiments in designing and printing a trefoil knot.</p><h4>Printing</h4><p>The version I show here is printed at 70% scale in PLA. Unlike my previous version, this one has a “skin.” Use the gcode or 3mf file to print a similar version in PLA. Alternatively, you can try other fill settings, etc. to create your own version.</p><p>Additional Notes :&nbsp;</p><ul><li>This was printed with no infill</li><li>The printing temperature was raised slightly in an attempt to improve the transparency effect</li><li>I recommend using supports to keep the print stuck to the bed</li><li>This version printed beautifully in transparent PLA with no defects</li></ul><h4>CAD</h4><p>Since making my initial design, I have improved the CAD files by adding additional parameters for modifying the basic design. In addition, I have created additional “profiles” (the shape of a cross section of the loop), which can also be modified parametrically.</p><p>The OnShape 3D CAD files here :</p><p><a href="https://cad.onshape.com/documents/f36468084e28f8df8fa36937/w/4ddd1ec94fcc3fbe8bf684cd/e/e203757048166706b080d91a">https://cad.onshape.com/documents/f36468084e28f8df8fa36937/w/4ddd1ec94fcc3fbe8bf684cd/e/e203757048166706b080d91a</a></p><p>&nbsp;</p>
