Dual Z Axis Ender 3 / 3Pro for square nut

It is an light remix.
i removed che brand name and make the mount curve from one side in way to improve mechanical resistance to different forces, also changed the nut mount, now it shoulkd fit the original or the squared POM nuts.
all holes are the same but just little bit bigger avoiding the neccessity of post processing, also other parts like spacers are the same but i just resized holes making them bigger.
Its pretty easy to mount but if u have doubts just took a look on the original design

i also include a motor mount i use, but u can easly find one here on thingiverse

Nut Mounting Holes Dimensions:

Central >10,5 mm
Side 3.5 mm
Distance of the side one(center) from the center hole 9.5mm
distance of the center of both side holes: 19mm
(Designed for Nuts i linked and compatible with orignal brass nut)

just remix it if u need different dimensions, its a 5 min deal since the are plenty of room Between vertical walls >28mm

Harware:
(2) M5 X 35 Cap Head Screws
(1) M4 X 50 Cap Head Screw (u can use the one from the x tensioner if u have the 3 pro and changed the tensioner to the printed one.)

IMPORTANT: since u will need to relocate your PSU here the prints i used
https://www.thingiverse.com/thing:4927477
But once relocated it WILL NOT BE GROUNDED ANYMORE, so u will need to PUT A WIRE FROM GROND to a NOT ANODIZED PART OF THE FRAME.
search on youtube for this.

NOTE: the file with spacers include all spacers u will need to print, and they are spaced in way to fitt arround the mount on the bed.

I SUGGEST you to print all the stuff in one go since dimensions could change if u will make adjustement to your printer, but at the same time all this stuff is not that dependent from each other, only spacers should be done in one go.

NOTE: None of those are some kind of affiliated links, i would like but i cant XD i post links only to give u an idea of what u will need, so check it before even start this progect, maybe it will be too much. (POM Nuts are something very good and pretty precise)

Feel free to comment, sudgest improvement and remix, if u are interested i could post the meshmixer file but only after asking the original designer for it.

NOTE it is work in progress because im still working on some details, but the general design is finished, Check my other remixes that will fit perfectly this upgrade.
