EGO Leaf Blower Nozzle Attachment

<p>[See "Does it work?" below before printing this!]</p> <p>This nozzle attachment is for the EGO cordless blower model LB5300 (see photos), but may fit other EGO cordless blowers as well; see the included drawing for relevant dimensions. This blower is sold without a nozzle attachment, and I did not feel like spending $13 to buy one (especially when it's more fun to make one).</p> <p>I ended up making three versions of this attachment:</p> <ol> <li>Nozzle with baffles and no rim</li> <li>Nozzle with baffles and reinforced rim around exit oval.</li> <li>Nozzle with no baffles and reinforced rim around exit oval.</li> </ol> <p>Note that the tube for the blower is made for a "bayonet" type attachment. To attach the nozzle fit the slot over the protrusion and rotate to lock in place.</p> <p>Does it work? My hope was that this would concentrate the air stream from the blower and make for a more concentrated and powerful air stream at a greater distance. I performed a crude test by blowing over a cardboard box from a distance, using both baffled and no-baffle nozzles, and with no nozzle; there was no significant difference among the three tests. The nozzle does appear to "concentrate" the air flow closer in, but it also makes the blower quite a bit louder. So I probably won;t be using this nozzle attachment much, if at all. On the plus side, I saved a few bucks by not buying one, and I had fun making it.</p> <p>The OnShape 3D CAD files for this are available here:</p> <p><a href="https://cad.onshape.com/documents/da7df4feb3480e66a648b21b/w/73e66cfb3e6e762c5c48ff0e/e/dd07c2bbebfa592ec3000990">https://cad.onshape.com/documents/da7df4feb3480e66a648b21b/w/73e66cfb3e6e762c5c48ff0e/e/dd07c2bbebfa592ec3000990</a></p> <h3>Print instructions</h3><p>Print in PLA using the included 3mf files; otherwise :</p> <ul> <li>Print oval side down</li> <li>Infill = 0%</li> <li>0.20 mm Quality</li> <li>for the "no rim" version use a brim, otherwise not needed</li> </ul>
