prusaprinters
<p>This is a modular 150mm air hose adapter, that simply screws on to common flexible 150mm spiral hoses. <br>These hoses are commonly used by portable AC units.<br> </p><p>The parts are done from scratch, but I did use the threads on the main adapter from <a href="https://www.thingiverse.com/thing:4519730">wejn's</a> design. <br>So a shoutout to him.</p><p> </p><p>In this design there are a few options to choose from to customize it:</p><p>-The length with the optional extenders<br>-A type of end piece/vent if you decide to use those.<br>-It's possible to add mosquito/insect netting to the end piece/vent.</p><p> </p><p> </p><p>-The "Main_Adapter" is one big piece which screws on to the end of the air hose, and ends with a narrow slot.<br>To the Main_Adapter you can then add a end piece/vent, extension or a combination of both.</p><p> </p><p>-The extensions come in three different lengths:<br>8, 12 and 15cm.<br>Secure it in place to the main adapter with a little bit of glue if the fit is to loose.</p><p> </p><p>-The end piece/vent comes in three different types:<br> -"OpenEnd" which has no louvres, but makes it possible to clamp mosquito/insect netting to the end.<br> -"HorizontalVent" which has one long horizontal louvre.<br> -"VerticalVent" which has five vertical louvres.<br>This part has a loose fit to the end of the main adapter/extensions in order to have clearence enough to clamp some mosquito/insect netting inside.</p><p> </p><p>Printing:</p><p>Nothing should require supports to print and I printed my parts out of PETG without any problems.</p><p>I used 5 perimeters (to get solid thin walls) and 10% gyroid infill.</p><p> </p><p>Post print:</p><p>I just used some cheap mosquito/insect netting that is normally used on windows with velcro strips.<br>Just cut a ~22x8cm rectangle of netting, trim the corners a bit and it should fit pretty well without sticking out underneath too much..<br>When the size and trimming seems good enough just add some glue around the brim and press the end piece/vent in place.<br>If there are any tufts of netting peeking out from underneath the edges just slice them off with a scalpel or sharp knife.</p><p> </p><p>General info:</p><p>The parts shown in the photos are:<br>-Main adapter<br>-8cm extension<br>-Vertical vent.<br> </p>
