Dell Laptop Air-Intake Spacer

prusaprinters

<p>It’s handy to use my Dell Latitude laptop sitting on its neoprene sleeve (e.g. on my lap) – but the soft sleeve blocks the fan intake. &nbsp;This spacer keeps a gap to let air in.</p><p>The lugs keep it attached to the E/Port connector (so works for Dell Precision E-Series, too), if you pop something like <a href="https://diy.bostik.com/en-UK/products/stationery-craft/removable-glu-dots">this</a> on the top of each lug. &nbsp;When you remove the spacer the dots will stay in the holes ready for next time.</p><h3>Print settings</h3><p><strong>Layer height</strong>: 0.2 mm</p><p><strong>Line width</strong>: 0.6 mm (my nozzle is 0.4 mm)</p><p>For the base, I used 19.9% Triangles infill with X/Y offset to line up nicely, with a single top layer of Lines running front-back (with part fan reduced to 50% to prevent pillowing) and no bottom layers. &nbsp;This gave a pleasing triangular-patterned base covered in a skin of separate (because line width &gt; nozzle diameter) lines that’s flexible (even in PLA), so doesn’t crack if bent a bit.</p><p>I used a <a href="https://support.ultimaker.com/hc/en-us/articles/360013370140-How-to-adjust-print-settings-of-a-part-of-my-model-in-Ultimaker-Cura">cutting mesh</a> in Cura for everything above the base, so that the base’s skin extended under the lugs, and to change the number of top layers for the lugs to a more solid 3 (and to set the unneeded infill there to 0%).</p><h3>How I designed this</h3><p>In Tinkercad. &nbsp;<a href="https://www.tinkercad.com/things/lIabJnjfNzN">Edit it online.</a></p>
