CLEAN/UNCLEAN dishwasher magnet

prusaprinters

<p>There are plenty of dishwasher signs on here, but I wanted a CLEAN/UNCLEAN one. &nbsp;:D</p><p>This works quite nicely if printed in two contrasting colors (see photos). &nbsp;You could also do a three- or four-color print, of course—just make sure not to skip the “Contrast Test” section, below.</p><p>This is designed so to be completed in two passes on a Prusa MINI (or in my case, one pass on each of two MINIs). &nbsp;I usually print at 0.25mm layer height because I'm impatient, so all relative heights here are multiples of that.</p><p>&nbsp;</p><h4>Printing</h4><p>Print one each of the CLEAN and UNCLEAN parts, and two of the CONTRAST parts.</p><p>&nbsp;</p><h4>Assembly</h4><p>NOTE: The CLEAN part has two tabs on the back. &nbsp;The other parts have slots that should help line everything up.</p><h5>Fit Test</h5><p>BEFORE YOU GLUE ANYTHING, try to snap all the parts together. &nbsp;Check:</p><ul><li>Does everything fit snugly? &nbsp;The CONTRAST plates will be fairly flexible, so you might have to wiggle them around to get their slots aligned around the tabs.</li><li>Check the orientation of the letters. &nbsp;The sides fit together in two different orientations, so pick the way that works best for you:<ul><li>If both words are “up”, you'll flip the sign horizontally (around the short axis).</li><li>If the words are upside down from each other, you'll flip the sign vertically (around the long axis).</li></ul></li></ul><h5>Contrast Test</h5><p>Holding all the parts together, take the sign into your kitchen. &nbsp;Check:</p><ul><li>Using your normal lighting, can you actually read the lettering on both sides?<ul><li>If you're using a light color for one of your CONTRAST plates, you may need to put a small scrap of paper or card stock behind it to bounce the light back.</li></ul></li></ul><p>Once everything looks good, take it all apart again. &nbsp;<strong>Make sure you keep track of the orientation of the CLEAN and UNCLEAN parts!</strong></p><h5>Magnets</h5><p>Push all eight magnets into their holes, then do another fit test. &nbsp;Put the CLEAN and UNCLEAN sides together face to face <i>(check the orientation again!),</i> and make sure the magnets pull the pieces together.</p><p><i>Pro tip: &nbsp;only the two magnets on each corner need to stick together. &nbsp;It might actually be a good idea to use opposite poles on the left and right sides. &nbsp;That way, if you get the orientation wrong, the magnets will push each other away.</i></p><h5>Glue (AKA “Point of No Return”)</h5><p>If you're using superglue, leave some room around the letters, since superglue can discolor some plastics. &nbsp;<i><strong>(Also, gloves are your friend!)</strong></i></p><p>Put the CLEAN part face down. &nbsp;Glue all around the letters and the outer edges.</p><p>Put the first CONTRAST plate down on top of the CLEAN part. &nbsp;Make sure the slots fit around the tabs on both sides. &nbsp;Press the plate flat and check for glue leaking around the edges.</p><p>Apply a thin layer of glue to the top of the first CONTRAST plate, then put the second CONTRAST plate down on it. &nbsp;Again, make sure the slots fit around the tabs on both sides, press the plate flat, and check for leaks.</p><p>Put the UNCLEAN part face down. &nbsp;Glue all around the letters and the outer edges. &nbsp;Then pick it up and <strong>check the orientation one last time.</strong> &nbsp;Snap it into place on the tabs, push it down <i>(you did check the orientation, right?)</i>, check for leaks, and clamp the whole assembly until the glue sets.</p><p>Enjoy!</p>
