This is a BL Touch Mount Bracket for the Ender 5 Pro. It features clamps that clip on the BL Touch so you will not use the bottom 2 screws, and a support for overall mechanical strength.
Warning: this is useful only for some printers where the BL Touch is lower than the nozzle, when mounted with the Creality-issued bracket.
It is quite far from the nozzle so you will have to adjust the printing plate cover accordingly.
The author marked this model as their own original creation.
