Pro-Tip:
you can scale the piece on the z-Axis for your demands in your slicer :)

Are you quite sure?

When I removed the upper bearings, I noticed that the right leadscrew has 3 mm less distance to the frame at the top than at the bottom.
This means that the Z motor must be placed 0.44 mm closer to the frame. But that's not possible, the motor is already sitting on the frame.
The left spindle has even 4 mm less distance at the top.

At least on my CR-10 it is the case. You have to consider that creality is improving their printers continuously.
The critical point to measure is the distance between the Z-Extrusion and the position of the Z-Rod Nut to the frame (not the position of the top bearing)

Hi! Do you happen to have the file for that golden motor coupler? Best regard!

1mm works perfectly for me. Thanks you MasterFx.

Can you create the yellow piece too?

Thank you for a wonderful work.
If you do not mind, could you tell me the print results using the work and the print results you do not use?
If there is a big difference in print results, I would like to introduce it to my printer as well.

So if I'm using a regular coupler, I don't have to worry about the lead screw offset? I was wondering, how did you measure that? I used the end of my digital caliper, but unless I measured incorrectly somehow, it looks like my lead screw is about half a millimeter further away from the frame at the bottom already..

The better the alignment the lesser stress you put on your coupler and maybe you even get better prints, because the leadscrew doesn't get that much force.
You can measure the offset when you remove the coupler and let the leadscrew "fall" onto the Stepper motor axis, like I did in image #3.
You can also use the play of the screws in the frame to align your stepper a little bit to the left/right but of cause you can't increase the distance to the frame, an this is this spacer is for.
