Dual 5015 Satsana Direct Drive w/3D Touch Front Mount and Drag Chain adapter for Longer LK5 Pro (Dual Blower)





Description
I needed to make this fit a Longer LK5 Pro with the factory dual backplate, as most shrouds designed with the CR10 or Ender 3 in mind don't have the same mounting hole pattern. In the process of that, I remixed this model along with the drag chain mount from https://www.printables.com/model/517504-my-lk5-pro-drag-chain-setup by CrunchBerry. There is a link there to the actual chain I printed as well (not part of this particular remix).
The main shroud has been altered to allow for use with the TZ-E3-2.0 High-Flow hotend, and will still work just fine with the factory hotend and most Mk8 style hotends - though you may need to add a couple of washers to the rear of those hotends for a straighter alignment with the extruder. As-is, the TX-E3-2.0 aligns perfectly. The 3.0 version might fit as well, but I have not verified that.
You can still print this relatively quickly and without support (as long as you have halfway decent bridging), as the printing gods intended :)
I didn't like the BL Touch/3D Touch mount eating up ~20mm of my x-axis, so I relocated that to the front of the shroud, using two set points for M3x4x4.2 heat set inserts and M3x6mm pan head screws. I also made the mounting plate with adjustable holes to allow for easy on-the-fly adjustments to the height of the BL/3D Touch without having to fiddle with any kind of spacers.
If you don't want to use the 3D Touch mount, no worries; the mounting holes to not open into the duct.
NOTE: This has been designed around the 3D Touch v 3.2 (NOT the Pro version, which is bigger {not sure what any other differences may be}). I have not tested a branded BL Touch.

I added a small hole inside the shroud to mount this 24v LED: https://amzn.to/4bdA5PF - it is just bright enough to illuminate the print head so you can see a little bit of what is going on under there (I will probably continue to work on this to add another or larger/brighter light).
I just connected the power leads to the primary (always-on) cooling fan power so that it comes on whenever the machine is powered on. To connect the two I installed JST XH 2.54mm female connectors with this kit: https://amzn.to/44pqBNP and plugged them both into this inexpensive y-connector: https://amzn.to/4waYygA
Everything fits nicely in the drag chain assembly.
The TZ-E2-2.0 hotend is performing amazingly; I have doubled my print speed compared to the red Mk8 all-metal hotend that I replaced. You can find it here: https://amzn.to/4wjKuSa ; or for less on AliExpress if you're more patient than I am!
