Numatic Henry/Hetty Hose Nozzle

prusaprinters

<p>The nozzle of my Numatic Hetty had a tear in it and was on its way to become unusable. I couldn't find a replacement part on Thingiverse, and Numatic only sells the whole hose.</p> <p>I designed this replacement part and it is a drop in replacement.</p> <p>Fusion 360 archive included to allow for further tinkering.</p> <p><strong>Update 2021-04-04:</strong> Uploaded a new version. The old version had a 0.5mm ring inside, but a tear/crack forms over time. The new has a 0.25mm ring, which suffices.</p> <h3> Print Settings</h3> <p><strong>Printer:</strong></p> <p>Creality CR-6 SE</p> <p><p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div><strong>Supports:</strong></p> <p>Yes</p> <p><p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2</p></div><strong>Infill:</strong></p> <p>20%</p> <h3> <strong>Filament:</strong> SUNLU PETG Grey <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>Print with 3 or 4 walls for optimum strength.

After this you can press the newly printed nozzle onto the hose. </p></div></p></p> Category: Replacement Parts
