CR-6SE: Hotend Fan Shroud (4020 Blower) + Near-End BMG Extruder Mount

This is my wife, she is really beautiful（￣︶￣）↗

I don't know if anyone still uses the CR-6SE, but I'm planning to switch to Bambu Lab. However, since I've already done some modifications, I'll share the model.

The original models are from Thingiverse: [CR6-SE] blower fan duct 40x20mm and CR-6 SE Direct Drive Mount; I combined these two models and added some other parts. Refer to the photos for details.

It's best to print with PETG to ensure structural strength!

Additional Materials Needed: 6x M3x10 screws, 3x M3x25 or M3x30 screws, 6x M3 nuts; 1m PTFE tube, CR-6SE original accessories, BMG extruder, one 4020 blower fan, 42 stepper motor extension cable (≥0.5m)

Installation Instructions:

After removing the original hotend and extruder, install as shown in the image (the self-provided screws are marked in the image; the others use the original machine's screws).

Remember to replace the extruder motor's cable!

There is a groove where the motor is fixed. This is a reserved slot for cable ties, preventing a lack of space for fixing cable ties when installing heatsinks on the motor.

Heatsinks or heat sinks can be installed separately; there is no mandatory requirement here.

Below is the installation of the cable duct:

Here, insert the PTFE tube fitting from the original extruder into the mouth on the inside of the cable duct, and then connect the PTFE tube to prevent the PTFE tube from loosening.

(⌐■_■)Is that a pneumatic fitting??

Secure the cable duct using M3 *10 screws and nuts (I used up the M3 *10 screws, here I used M3 *30).

If you are using AMS instead of the original filament holder, you can attach this cover to the filament runout sensor (this is unnecessary if you are using the original filament holder). Similarly, insert the fitting first, then connect the PTFE tube.

The heatsink next to the motor was also added by me (*￣3￣)╭

Finally, organize the wires.

Many thanks to the original model's two creators, konton and michaelbourque, for sharing their models!
