Portable extractor fan and ducting

prusaprinters

<p>I have a very small workshop in a shed in my Garden. Space is at a premium, so when things aren't being used they need to get put away, and when they are used they tend to have to do double duty.</p> <p>When I run my machinery, I don't used coolant as it's messy - but I do used cutting oil. This tends to smoke when machining parts and sometimes it fills the workshop. This is where the extractor comes in.</p> <p>It's a standard 100mm inline bathroom extractor fan mounted on a piece of board. The STLs included in this thing are the parts I designed to make it reposition-able and to make it easier to store.</p> <p>These parts are:</p> <p>A flanged port that is screwed to the shed wall<br/> A cap for the port so it can be closed when not in use<br/> An adaptor tube / coupler for the ducting to the port<br/> A ring clamp for the business end of the ducting to hold the inlet next to the work via an articulated magnetic indicator base.<br/> A flanged box to house an illuminated rocker switch which turns the extractor on or off.</p> <p>The whole thing can reach anywhere in the workshop, and can be packed away and hung on the wall when not in use.</p> <p>New Files Added 19/03/20 - I have modified the duct coupler to add a small lip on the end to stop the ducting from slipping off once zip tied on. This the V2 file.</p> <p>I have also created two new inlets: A full conical one and one that is cut to for more of a hood shape due to the cone being cut at an angle. Both have the same sort of lip as the coupler to prevent duct slippage; both are the base diameter for use with the 100mm ducting.</p> <p>06/04/2020 - new V4 duct clamp part - this uses a single M5 screw to tighten rather than two M3 screws on the previous version.</p> <p> <figure class="media"> <oembed url="https://youtu.be/l83bQI1WAzk"></oembed> </figure> </p> <h3>Print instructions</h3><h3>Category: DIY Summary</h3> <p>I have a very small workshop in a shed in my Garden.
