Ender 3 - Satsana Fan Duct / BLTouch / Direct Drivinator

thingiverse

Enhance your Ender 3 / Ender 3 Pro with direct drive, a BLTouch, and improved airflow, all at once! This uses 100% stock parts, though you will need three extra m3 screws: two for securing the BLTouch (I used m3x6) and one for attaching the fan housing to the direct drive adapter (I used m3x8). I've been happily using the [Direct Drivinator](https://www.thingiverse.com/thing:3589452) for months, and I wanted to try adding a fan duct. I found an interesting remix of the Satsana duct that holds BLTouch even closer than the stock bracket, which allows you to probe a larger area. I printed it and it works flawlessly for me! EDIT 1: If you're looking for a fan cover to get rid of those silver screws, I would personally recommend the [Satsana Honeycomb Fan Cover](https://www.thingiverse.com/thing:5197467) by Landon_L. EDIT 2: I noticed some issues with my extruder when printing some especially squishy TPU, so I bought the [REDREX Dual Gear Extruder](https://www.amazon.com/dp/B09ZDQM6P6) to help compensate. Unfortunately the hole was in a different place compared to the stock extruder, so I modified the Direct Drivinator to slide the bracket backwards so the holes would line up again. If you happen to be using the same dual gear mod that I am, you should download that version.
