[UPDATE Feb 12, 2021]: Uploaded the .step files for the duct and the cap. [UPDATE Jan 28, 2021]: The duct needs **NO supports** for printing. Please **rotate** the model in your slicer **for 90 deg**, so that the **mounting side** of the duct is **facing down**, and the **opening for the fan is facing up**. Thanks! [UPDATE Jan 4, 2021]: I added a fan guard to the 4020 from Rom1330 (Thanks for that!) https://www.thingiverse.com/thing:1244751 I love the design of the Satsana 5015 fan duct, and I wanted it for my Micro Swiss DirectDrive Extruder with All Metal Hotend. But it was originally missing two important features: - a BLTouch mount. - And further I couldn't find a remix which allows for installing a 4020 fan nicely. Thus, I re-designed the Satsana fan duct a tiny bit and extended the front for 10mm to encompass my [Sunon 4020 fan](https://amzn.to/3aN056r) and added a chamfer around the extension. Now the whole fan is nicely fitted to the front and the chamfer makes the extension less "visible" (at least from my perspecive :). Additionally, I found a great BLTouch mount that allows for mounting the probe to my [Sunon 5015 blower](https://amzn.to/3nHW4Uj). (Credits to andy_spoo for https://www.thingiverse.com/thing:3718029), but I extended the bottom part of the bracket to 5mm to have more clearance for the nozzle while probing. Here the **offsets** of the BLTouch: x= +56 mm y= -33 mm Sorry for the cable mess...I'm waiting for a cable conduit in light blue ;-)
