This is a fan duct supporting a 5015 fan and BLTouch for the E3D Hemera and Revo. It's installed on a ShadowMega RadZ_K (a heavily modified M3D Promega running Klipper). I've also included a mount for the ADXL345 accelerometer that goes directly on the Hemera stepper motor. The BLTouch is relatively close to the nozzle, although space for the screws are a bit tight. The duct uses four 3x5mm heatserts, two for the BLTouch and two for the fan, and the ADXL345 mount uses two more. It's pretty solid.
It can be printed with very little support by tilting it 45 degrees with a brim, although lately I print it with the front (where the fan mounts) flat on the pate and let it build supports. Be careful the supports don't clog the air paths for the fan inside the model if you print it this way.
Note the Duct file from Fusion360 had some issues the one I've included was repaired in Microsoft 3D Builder. This version is also about a tenth the size after repair :-)
