Satsana Duct Remix for Ender 3v2 - integrated BLTouch mount (4010 + 5015 fans)

thingiverse

This is a BLT-friendly remix of the very excellent [Satsana duct](https://www.thingiverse.com/thing:4369859) for Ender 3 series (including v2), for use with a 4010 hot-end fan and 5015 blower. The model preserves the original offsets I used for the BLT mount (X-42.00 Y-10.00) with my OEM Creality duct. Once installed, you'll need to flash your machine with: `M851 X-42.00 Y-10.00 \ M500`. The remix combines elements from two preexisting models while overcoming some minor deficiencies: — [This model](https://www.thingiverse.com/thing:4637453) preserves the original Satsana duct sizes (symmetrical on both sides), but at the expense of a larger X offset of -46mm. Even with that offset, the BLT needs to be reversed (wiring connector on left side) to fit. — [This model](https://www.thingiverse.com/thing:4647053) seems to be the most popular, but has two minor issues: (1) a separate mount that required X carriage wheel disassembly to install and (2) not enough clearance (even with the narrowed left duct and extra 1.65mm X offset) for the wiring connector on the BLT. My remix "welds" the BLT mount to the Satsana, preserves the 42mm X offset, and avoids the carriage wheel bolt altogether. Note that it does use non-OEM M3 bolts and locking nuts. There's a nice diagram [here](https://www.thingiverse.com/thing:4647053) showing mounting hole patterns for different machines I've included pics of my setup. I used a 24V 5015 (relying on OEM wiring). The Noctua 4010 is 12V, requiring a buck converter. I've also included files for the honeycomb grille covers I made for both fans. The 4010 friction fits while the 5015 mounts with the fan screws. Finally, I included the original [cable cap](https://www.thingiverse.com/thing:4369859) so that all components are in one place. My BLT is mounted with this ingenious version of [the shroud](https://www.thingiverse.com/thing:4634422) (version 10, I believe), and Z-scaled [spacer](https://www.thingiverse.com/thing:3466223). This worked very well for me, and has remained sturdy/stable over the past month. Use at your own risk, though! Many thanks to Eric Anastas for the original design, the folks that contributed to the linked remixes, and a variety of other people on Thingiverse and Reddit who contributed ideas. _**[NOTE: I received a few requests to remix a version with the OEM parts cooling fan. I quickly synthesized my remix and the Satsana for OEM blower, and uploaded a file labeled "TEST". I have NOT printed or tested it myself. If you do test it, please let me know your experience.]**_
