<p>DEPRECATED DESIGN</p> <p>Please be aware I am not developing this design any further.</p> <hr/> <p>Microswiss_Cooling_Side_v1.1.stl for side mounting cables now uploaded.</p> <p>Upgraded features are as follows:</p> <ul> <li>better nozzel visability</li> <li>an extra parts fan screw hole for stronger fan fixing</li> <li>more space between parts fan the mounting plate surface</li> <li>more defined jets to nozzel</li> <li>BLTounch mount adjusted for less supports when printing</li> </ul> <p>Hotend cooling duct replacement for the Ender-5+ with the Microswiss DD upgrade using stock fans v1.</p> <p>I was not happy with the inefficient stock E5+ hotend cooling setup attached to the Microswiss DD full metal upgrade I did... so I redesigned the cooling duct with the stock fans in the same orientation.</p> <p>I included in the design a vertically fixed positioned BLTouch bracket and cable strain relief for cables coming from the right hand side. Vertical entry cable strain relief for rear cable position coming soon. I have included a 1mm BLTouch packer if required so remember to adjust your z-offset.</p> <p>I printed 5x prototypes each around a 5-6 hour print time until I was satisfied with the final design and clearances from my designed part to the hotend. This part does not impact anywhere on the machine.</p> <p>There's a 2-3mm clearance from the printed part to the silicon sock and with testing for 30min at 230°C no melting occurred with PLA+, so far. Recommend printing in a higher temp resistant filament though.</p> <p>There are two flat surfaces to print from making it your choice which orientation you want to print it. I'd recommend using tree supports using Cura either way.</p> <p>Also tested the airflow angle of the 2 part cooling nozzels with the water dimple test, resulting in the dimple right under the hotend nozzel.</p> <p>Anyway this design works for me. Have fun and donate if you think my time was worth it.</p> Category: 3D Printing
