Eliminates play in the Z-axis and holds it in place.

Due to my design I placed them upside down. They work great and hold the Z axis tight, eliminating a bit of play. If I rebuild my other two printers I will buy more for them.

Pros
  • pitch: 2 mm; Lead: 8mm
Cons
  • Quick Guide

Anti-backlash nut Not suitable for Ender 3

In general, there are no questions about the quality, it works as expected. But the anti-backlash nut doesn't fit the Ender 3. I just turned one of the sides and made the screw holes bigger. Screws and nuts for fastening.

Pros
  • High quality anti-backlash nut, high precision, suitable for T8 lead screws of 3D printers.
Cons
  • Long delivery time

Works as it should: Linear motion lead screws

Fits the Ender 3 Pro very well. I have found that after with almost any printer system changing with ever-tightening tolerances, there are common design flaws. I'm not saying the Ender 3 Pro isn't a great printer at a fantastic price - it definitely is! This is the definition of a truly expandable platform with unlimited possibilities. My Modifications or "upgrades" are too numerous to list ad nauseam, but I've noticed that the Z-axis transitions have a slightly uneven adjustment.This isn't…

Pros
  • Coupling dimensions: 19mm x 25mm / 0.75 x 0.98" (D x H)
Cons
  • Unbelievable price
