K40 4" vertical exhaust

prusaprinters

<p>Easily removable two part 4" (100mm) vertical K40 exhaust - port and duct with optional gasket</p> <p>I've included a version of the duct with manually added support which saves on time and material</p> <p>The optional gasket is 1mm thick and fits both between the port and the K40 chassis and between the port and the duct - use two if you'd like. OR you could just trace out a paper gasket or some other material.</p> <p>I drew inspiration from these designs: <a href="https://www.thingiverse.com/thing:3460670">https://www.thingiverse.com/thing:3460670</a>, <a href="https://www.thingiverse.com/thing:1627210">https://www.thingiverse.com/thing:1627210</a>, <a href="https://www.thingiverse.com/thing:2748726">https://www.thingiverse.com/thing:2748726</a><br/> Credit to those designers.</p> <h3>Print instructions</h3><p>Print standing up from the base.<br/> I printed with 5 perimeters and 5% infill - pro tip: use more perimeters for more strength, infill does very little.</p> <p>Remove the original fan port. Add two M3 bolts from the inside out and fasten with hex nuts - line the hex nuts pointing horizontally. Add gasket. Slip the port in from the back. Add gasket. Attach the duct and fasten with hex nuts. (See pictures)</p>
