<p>An intake funnel/tract for the hotend cooling fan of the Prusa i3 mk2s.</p> <p>By gradually decreasing the cross-sectional area towards the fan and ducting the air into the fan blades, the performance of the fan increases. The funnel is cut on one side so it doesn't hit the leadscrews when the printer homes.</p> <p>It consists of 2 parts: The main part is the funnel which bolts on the outside of the fan and the secondary part is a cover that closes the holes in the fan that is needed for the bolts. The cover clicks into the bolts and sits in place by itself.</p> <p>The funnel can be printed without support but the cover needs support. The funnel should be printed with the flat side down.</p> <p>Edit: I noticed that I initially uploaded the wrong version of the cover. V2 is the one I have on but a part of it broke off while it printed and I thought it looked nice, so I added a cutout to V3 which is similar to the part that broke off of mine.</p> <p>I've added a V2 of the funnel so it is made to be as big as possible with the backside in place while still allowing the x endstop to be reached. The backside is a dome held in place on the hotend side of the fan to improve the airflow after the fan.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>i3 MK2S</p></div> <p><strong>Rafts:</strong></p> <p>No</p> </p> Category: 3D Printer Parts
