Activated Carbon Filter

prusaprinters

<p>This is a remix of Deltapie's “passive activated charcoal filter” (found here: <a href="https://www.printables.com/model/119879-passive-activated-charcoal-filter),">https://www.printables.com/model/119879-passive-activated-charcoal-filter),</a> but with a screw-on top to allow for the easy exchange of carbon. &nbsp;Construction is exactly the same as before, but I'll rehash it here:</p><p>For the base, I'd recommend rotating it to the smooth side as bottom, 20 to 30% infill, at least 3 to 4 layers for the top and bottom shells, and at least 3 wall layers.</p><p>For the support, print six supports vertically with 0% infill and no shell layers for the top and bottom. &nbsp;I printed with 3 wall layers, but that may be too rigid.</p><p>For the lattices, print six of them with the widest layer rotated to the bottom. &nbsp;Ensure that you have no layers for the top and bottom shells, at least 2 wall layers, and print with 30 to 50% infill (dependent on the carbon pellet size that you want to put in). &nbsp;I printed with 30% infill with a tri-hexagon pattern.</p><p>The screw-on top can be printed in place. &nbsp;I printed it with 20% infill, 3 layers for top and bottom, and 3 wall layers. &nbsp;I did not support the screws for the cap, and it required a bit of clean up. &nbsp;You might require supports. &nbsp;YMMV</p>
