Lightweight fan mount (Ender3, CR10 etc.)

My goal was to create a lightweight fan mount for my CR10. 
I think it works fine with other Creality models too (ender 3 etc).

My goal was to have the BL touch close to the extruder and the overall weight of the whole assembly close to the X axis mount. It clears the mounting so that you can use the whole print area, and the mount is as low as possible to allow for tall prints.  

The hight of the fan duct, and BL touch mount, is modeled to match a 5015 blower fan and 
TZ E3 3.0 Hot end. 
This is the version (clone i guess) i use.

The base require a 40mm fan to gain rigidity. I use Noctua NF-A4x10 but you can use a deeper one too. 

It also requires a 5015 blower fan if you want cooling. I found a single fan enough for the prints i do. 
I get ca 16mm3 flow rate on my CR10 using PLA. 

There are two versions of mounts for BL touch. One with mounting for ADXL345 board for input shaping.
Offset is x:-26.9, y:-7.3 mm

Some of the original screws can be re-used. You also need
2 x M3x10 for BL touch 
2x  M3x5 (or longer) for ADXL345
4 x M3x15 (or longer) for the 40mm fan
2 x M3x20 for the 5015 fan

10 M3 heated inserts. 
for the 5015 fan and ADXL345 you need 3 mm long ones, for the 40mm fan and BL touch you can use longer. 

UPDATE:
2025-12-25 - Added mouting / holder for inductive sensor probe. I'm using a cheep LJ12A3-4-Z/BY i found on Amazon.
