<p><strong>12 most common magnet size holes (flush and embedded) provided in Files.</strong></p><p>These voids are created by an <a href="https://openscad.org/">OpenSCAD</a> script that will create &nbsp;cylindrical holes to be used in creating a negative space in your model that fits a cylindrical magnet to make your 3-D printed object magnetic. &nbsp;<a href="https://www.prusa3d.com/page/prusaslicer_424/">PrusaSlicer</a> has provisions to ‘Add Negative Volume’ to an existing object. &nbsp;May work with other slicers.</p><h5>External Magnet</h5><ol><li>&nbsp;After printing, use a little superglue in resulting hole, put magnet in hole. &nbsp;<i>&nbsp;</i></li><li><i>&nbsp;**let glue dry thoroughly</i>** (CA glue can cause white deposits)</li><li>&nbsp;Object will now stick to ferrous objects and surfaces.</li></ol><p>Resulting hole has tolerance specified slightly larger than actual magnet dimensions to allow for proper fit in printed part.</p><p>Example listing of <a href="https://amzn.to/3mtJjO4">magnets</a> that are available on Amazon.</p><h5>Embedded Magnet (-embed-) in filename below</h5><p>If a z height offset is specified in OpenSCAD script, the magnet hole will be placed offset “up” (away from printbed) inside the model, rather than on the outer (slicer bottom) edge. &nbsp;Use your slicer's ‘pause’ capability to stop the print (stop at (before) the layer that would enclose the magnets), insert the magnets, then resume the print.</p><h5>PrusaSlicer (Pause) Instructions</h5><p>(after adding negative volume to your objext, press Ctrl-6 to enter preview mode.</p><p>Slide arrows (on right side of window) up and down to find the layer that will draw the ‘lid’ above the magnets. &nbsp;While that layer is selected, right-click on the orange plus sign, then choose “add pause print (M601)”.</p><p>Slice as normal.</p><h3>Print instructions</h3><p>Download. &nbsp;Insert .STL as a Negative Volume in <a href="https://www.prusa3d.com/page/prusaslicer_424/">PrusaSlicer</a>. &nbsp;Slice your object. &nbsp;Print.</p><h3>Summary</h3><p>A hole generator to make a cylindrical hole for a magnet in your model. &nbsp;Can be flush on print bed or inside model (use <a href="https://www.prusa3d.com/page/prusaslicer_424/">PrusaSlicer</a> print pause to pause, insert magnet, continue print.)</p><h3>How I Designed This</h3><p>Designed from scratch in <a href="https://openscad.org/">OpenSCAD</a>. &nbsp;If you need custom design/modelling work done, feel free to drop me a line to request a quote. &nbsp;Valuable suggestions for improvement from <a href="https://www.printables.com/social/15113-steves42/about">SteveS42</a>.</p><h3>Actions:</h3><h4>Download</h4><p>Take this model for a ride on your printer. &nbsp;Post a photo of your prints as a Make.</p><h4>Modify</h4><p>If you feel the calling, edit and improve the design and post your results.</p><h4>Feedback</h4><p>If you have any questions, suggestions, or problems that you'd like to discuss with me, please feel free to <a href="https://www.printables.com/messenger/new/6231">message me</a>. &nbsp;I'm always willing to discuss my models, your ideas, 3-D design, and 3-D printing.</p><h4>Explore</h4><p>Check out <a href="https://www.printables.com/social/6231-layerworks/prints">my other models</a> here on Printables.Com.</p>
