Ender 5 Pro Dual Z [TESTED WORKING]

Compared to other designs on printables, this is the one you searched for. It uses all the stock parts from ender 5 pro z axis. You only have to order duplicates of the original parts. The model is partly remixed from Voron Legacy Z axis, but I still had to change a lot.

Here is the list of stock parts it uses:

 - ender 5 pro 2 z axis extrusions (NO CUTTING NEEDED)
 - 2 linear rods
 - lead screw
 - all z drop brackets with no need to order new
 - stepper motor
 - 2 stock bearings lm10uu 10x19x55 with collar (to make it cheaper you can order 2 more without collar, but for nicer look I recommend using 4 without collar because its not needed)

Here is the list of parts you need to order:

 - 4 x lm10uu 10x19x55 bearings (you can order 2 to make it cheaper)
 - 2 x linear rods 10x435 mm (you can order longer and just cut them)
 - 1 x TR8 lead screw with nut 2 mm pitch 365mm length
 - Nema 17 stepper motor

Here is the list of fasteners you need to order:

 - 20 x M5 Roll-in Nut (for the z drop brackets because originally they are screwed to the frame)
 - 20 x M5x12 screw (for the z drop brackets)
 - 5 x M5x25 screw (for the lead screw block)
 - 20 x M4x22 screw (for the arms, also the arms are screwed to the extrusions)

NOTE

The stock brackets are mounted in the bottom, and at the top of the frame I use 3d printed ones. I recommend the Mercury One Z drop brackets. I could publish them here but you can download them from their website:

Please ask any questions in the comments I will respond fast.

UPDATED FILES: the arms don't have to be mirrored for proper hole alignment,  added separate files for each arm, included updated f3d files.

 

I used part of the arms from voron legacy dual z, the bearing mount and part of the design.
