<p>This part cooling solution is intended to be used with one of my print head designs for the JGAurora A5:&nbsp;</p><ul><li><a href="https://www.printables.com/model/221408">E3D V6/Revo Six Hotend with Zesty Nimble Remote Direct Extruder V1.2</a></li><li>E3D V6/Revo Six Hotend with The Orbiter v1.5 140g Dual Drive Direct Extruder (not yet published)</li></ul><p>This is my first attempt on a fan duct with assistance of CFD-simulation (provided by <a href="https://www.slimscale.com/">simscale</a>). There is some room for improvement but overall the part cooling is quite OK in most cases.</p><p>I printed my first prototype in PLA, which is still in use after over a year now. A slight warping on one of the air-ducts was easily fixable with the careful use of a hot-air fan. Nevertheless, printing in material with more thermal stability is advised. Print with supports.</p><h3>Mounting Variants</h3><ol><li><a href="https://www.printables.com/model/221408">JG Aurora A5 printhead with E3D V6/Revo Six Hotend and either bowden or Zesty Nimble extruder</a><ul><li><i><strong>FanStrutL-JGA5v6</strong></i></li><li><i><strong>FanStrutR-JGA5v6</strong></i></li><li><i><strong>LowerFanBracket-JGA5v6</strong></i></li></ul></li><li><i><strong>E3D V6/Revo Six Hotend with The Orbiter v1.5 140g Dual Drive Direct Extruder</strong></i> (not yet published)<ul><li>t.b.d.</li></ul></li></ol><h3>Additional Parts</h3><ul><li>2x M3x6x4.2-3.6 threaded insert</li><li>4x M3x8 hexagon socket head cap screw</li><li>1x M3x40 hexagon socket head cap screw</li><li>1x M3 locking nut</li></ul>
