2-Pack Upgrade 2-in-1 Ender 3 Oldham Coupling Z axis 8mm Lead Screw Nut for CR10 S4 S5 Ender 3 Pro V2 Neo Series Ender-3 S1 Pro CR10S PRO 3D Printer (2)

The center distance between two holes is 18mm, fixing hole is M3, Used with 8mm lead of thread T8 screw

• This Upgrade nut combines the lead screw nut and oldham coupling into 1 set, smaller, lighter
• The Oldham coupling is made of brass, reduce friction and has sufficient strength, produced by CNC machine, high precision to make the connection gap between three parts lowest, low movement of inertial
• If the lead screw is not straight, the printing precision will be a problem, then this kit will solve it. high torsional stiffness, Protect driven parts and support bearings, used to advoid the effects for large radial misalignment
• Its function is to improve the printing quality from the problems caused by the swing of the heat bed during printing, like subtracting the effects for the clearance of not straight lead screw when printing
• The lead of thread is 8mm, The center distance between two holes is 18mm, fixing hole is M3, Used with 8mm lead screw
• Compatible with Creality CR10 CR-10S Pro Ender-3 ENDER 3S Ender 3 Pro, Ender 3 V2, Ender 3 S1 series, Ender 3 Neo Series 3D Printer and other 3D printer which lead screw fixing holes is M3 and two holes distance 18mm
