Functionally generated plot of sin(r)/r

<p>I previously tweeted about this here:</p><p><a href="https://twitter.com/rwhb2/status/1331992852532957188">https://twitter.com/rwhb2/status/1331992852532957188</a></p><p>but now I've implemented it in OpenSCAD so it is printable and tweakable!</p><p>The height is a function of the sine of the radius from the centre of the plot, divided by the size of the radius, i.e. sin(r)/r.</p><p>There are two different versions here, both “coarse” and “smooth”, along with the code to generate them.</p><p>The “coarse” version (the yellow one in my pics) is arbitrarily highly pixelated. The version I've uploaded has a “step” of 20 which makes for a nice little “pixel-art” desk ornament when scaled to around 6 or 7 centimetres on a side.&nbsp;</p><p>The “smooth” version (the turquoise one) is much higher resolution and has a different implementation, using the super-helpful <a href="https://github.com/rcolyer/plot-function">OpenSCAD Function Plotting Library by Ryan Colyer</a>. As Ryan has kindly released the library under the CC0 license, I have included a copy in the downloads section here.</p>
