Review on 🖨️ 3D Printer Accessories: T8 POM Anti Backlash Nuts with Elimination Gap and Spring Loaded Design for Acme Threaded Rods by Tony Wylie

Do your research. If you have ordered this and find it does not fit please ensure they are shipping you the correct items. 2mm lead - 1 start 4mm lead - 2 start 8mm lead - 4 start DO NOT buy these items) In my original 4mm wire order I received 3 2mm wires and 1 8mm wire. Obviously it didn't fit. I suspect others have experienced this issue and returned the package with no explanation, resulting in the wrong part being re-shipped. Replacement parts were perfect, no mud, great fit, super easy mod. This will make your Z jumps bug free!
