YOTINO Anti-Backlash 🔧 Elimination Diameter Material Set【2PCS】 Review

A nut is supplied with 4 starts for correct top and bottom. The other, the bottom one, has only 2 entries and cannot be screwed onto the 2mm lead screw. Let's see if the replacement is better. Edit: Changed from 1 star to 3 stars. The replacements were all 4 runs and correct.

I bought this to keep my Z axis upright and not fall off. The install went fine except the ones I had were unthreaded. So the Z-axis is up. There was a slight improvement, but it did very little to prevent the fall. Would I buy this again? no I bought it because TH3D is out of stock. I would buy it instead.

I bought them to put on my Cr-10 v2. They appear to be well made and easy to adjust to fit the printer. You'll need to file/cut/sand the side of them to make one of them fit onto the lead screw next to the stepper motor. On a bolt with nothing near the nut, you don't need to change it. They are made of brass so soft and easy to work with. I bought a second set to have one for my Ender 3 with an extra for a future printer.
