<p>I thought this would be a nice way to demonstrate polar graphs to my kids. <a href="https://www.desmos.com/calculator">Desmos</a> makes graphing polar coordinates ridiculously easy. Add a variable that creates a nice 3d printable transition</p> <p>Make a nice graph. Then add a variable (ie 'j' or 'k') that creates a nice 3d printable transition.<br/> Copy this as a new function in the openscad file:</p> <p>function newpolarfunction(z,t) = let(tt = z % 2 == 0 ? t<em>tstep : (t+shift)</em>tstep, j = <range iterate="" over="" the="" to="" variable="" which=""><em> z/zmax - <initial of="" value="" variable="">, k= <additional if="" required="" variable="">, rr = <scale></scale></additional></initial></em> <add function="" polar=""> ) ) [rr<em>cos(tt),rr</em>sin(tt),z*zstep]; Comment out the current function at line 106 and add the "newpolarfunction(z,t)"</add></range></p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Monoprice</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>Select Mini</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Infill:</strong></p> <p>50</p> <p><strong>Filament:</strong> Any PLA Any <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>Should be printable without needing supports.</p></div></p> </p></p> Category: Math Art
