<p>This was migrated from my Thingiverse profile and is from 2016.</p><p>Hot end heat sink enclosure and ducts for Ormerod 2 quick-set dual-nozzle setup with <a href="/dc42/about">dc42's</a> improved <a href="https://miscsolutions.wordpress.com/ormerod-hot-end-board-v2/">differential infrared height sensor board</a>.</p><p>A removable shutter allows airflow to be directed at the nozzles (for PLA) or upward (for ABS). Or both at a reduced rate (shutter removed completely).</p><p>You will need to rotate the heatsink 90 degrees so the fins are vertical. A third hole will need to be drilled into the heatsink to allow for the bolts. You will also need to widen the holes for dc42's sensor board (I used a 2 mm drill) and possibly those for the fan bolts (I used a 3.5 mm drill).</p><p>This design is completely parametrised (and I mean completely, everything from dimensions, to number, offsets and symmetry [or lack of it] of top and bottom vents, ducts, and duct geometry) so I should be able to change a few numbers to generate versions for the old-style one-piece nozzle or single-nozzle hot ends. I'll post them on Thingiverse in the near future.</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>RepRap</p><p><strong>Printer:&nbsp;</strong></p><p>Ormerod 2</p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>No</p><p><strong>Notes:</strong></p><p>ABS standard settings</p><h3>How I Designed This</h3><p>Designed in OpenSCAD, sliced with Slic3r.</p><p>&nbsp;</p>
