Micro Swiss Ender-3/CR-10 NG Fan Shroud (Noctua Remix)
Description
This is an *extremely* simple remix. The only change made from this shroud compared to the factory NG fan is that the rounded corners in the heat sink fan cutout are replaced with sharp corners. This allows you to install not only Noctua fans, but any fan with square (or at least less rounded than factory) corners. Other than that, everything else is the same as the original Micro Swiss design. Settings: - Supports: Yes (touching buildplate only) Everything else is up to you according to preference. The settings I used specifically are listed below. Additional modification required: - The top-left corner of the fan (only at the mounting point) may need to be cut or filed down to be made flush with the rest of the shroud. This is a tiny amount of material on 4020 Noctuas and is not visible while installed. - If using a Noctua or any other 12v fans, a 24v-12v buck converter needs to be installed before plugging into the printer. Look up any "how to install Noctua fans on Ender 3" guide online; they'll give you detailed instructions on how to do it and links to buy the converters. Notes: - Unlike stock Ender setups, this shroud design *completely* isolates the airflow between the heat sink fan and the cooling fan. If your ABS, ASA, or other high-temp prints were coming out great before installing this extruder kit and then come out like garbage after installing it, that's because your prints were receiving a slight cooling effect from the factory heat sink fan. If you're losing your mind trying to figure out why your prints are coming out horribly, turn your parts cooling fan on. Trust me on this one. 30% fan speed works well for me. - I print mostly high-temp stuff and don't need a beefy parts cooling fan. If you primarily print PLA and want to use a beefier parts cooling fan, there are other remixes out there that use better parts cooling fans; check those out first.
