Parametric Trash Can Ring

prusaprinters

<p>Nice trash cans come with a ring that goes around the ring to keep the bag in place and not hanging out the sides. &nbsp;Have a not-nice trash can? &nbsp;Print this and upgrade.</p><h3>Customizing This Model</h3><p>Don't print the STL - instead, open <i>Trashcan Ring - Parametric.scad</i> in <a href="https://openscad.org/">OpenSCAD</a>. &nbsp;You'll see a sidebar on the left called “Parameters.” &nbsp;Fill that in, press F6 to render the model, once that's done press F7 to export an STL.</p><p>The photo “measurements” shows what to measure for each parameter: the diameter of the trash can for <i>outer_d</i> , the width of the rim (on which the printed ring will sit) for <i>rim_w,</i> both in millimeters. &nbsp;Making the ring a bit too small is better than making it a bit too big, as a too big ring won't fit and a too small ring will simply move around a bit when putting it in place.</p><h3>Printing Advice</h3><p>Flip the model upside down so it doesn't need supports.</p><p>Print with as large a layer size as you'd like - this isn't a precision model, it's two cylinders with another cylinder cut out of them.</p><h3>Limitations/ Further Improvements</h3><p>This is only for round trash cans at the moment because I'm not sure how to mathematically describe or even accurately measure the other common shape, a rounded rectangle.</p><p>This needs a print bed as big as the diameter of the trash can. &nbsp;The trash can I wanted to make this for was just barely small enough to fit on my Ender 3. &nbsp;If you want this but your print bed is too small, leave a comment and I'll make a version that prints in quarters and sticks together with pegs.</p>
