Since there was no other BLTouch mount for the Ender-5 I remixed one for CR-10, I used Tinkercad so sorry for the model's not phenomenal quality but hey, it gets the job done. Just add one washer per BLTouch screw and you should be all set.

I'm also uploading Marlin 1.1.9 configuration - which I edited starting from Kevin Lau's version that I downloaded from the Facebook group. I preserved SD Card functionalities and obviously all thermal protections - I was inspired by this video by Teaching Tech https://www.youtube.com/watch?v=ocAeZRPVusw The offsets should be right but feel free to publish a comment if something's wrong!

• To burn the bootloader I followed this guide: https://www.instructables.com/id/Flashing-a-Bootloader-to-the-CR-10/
• To install the BLTouch clone I followed this other guide: http://3dprintlove.com/3d-printing/adding-bltouch-to-creality-3d-printer-ender-3-for-auto-bed-leveling/

Some notes:

• I did not have the board to avoid cutting the wire to the pin 27 so I just fiddled with the multimeter and found out that the cable I had to cut was the red one :)
• Remember to add G29 immediately after G28 in the start gcode!
