2-in-1 T8 Round Oldham Coupling Nut (16 mm center distance)

Upgrade your 3D printer with a compact 2-in-1 solution that merges the lead screw nut and Oldham coupling into a single, lightweight set. The brass Oldham coupling is CNC-machined for precise tolerances, delivering the smallest possible gap between the three parts and minimal inertial movement. If your lead screw isn’t perfectly straight, print accuracy can suffer—this kit is designed to counteract that, boosting consistency without adding bulk to your Z-axis assembly.

• Brass Oldham coupling to reduce friction while maintaining strong torsional stiffness
• CNC-machined for tight tolerances and the smallest connection gap
• 8 mm lead screw compatibility; center distance 16 mm; M3 fixing holes
• Protects driven parts and supports bearings by tolerating larger radial misalignment
• Improves print quality by compensating for heat-bed swing and lead-screw wobble during operation
• Designed for use with 8 mm lead screws in T8 systems
• Compatible with Voron VzBot BLV 3D Printer and other printers using T8 8 mm lead screws

2-in-1 Square Oldham Coupling Nut (18 mm center distance)

Same 2-in-1 concept, but with a slightly different footprint to fit printers requiring a center distance of 18 mm. The upgraded nut continues to combine the lead screw nut and Oldham coupling, delivering reduced friction, precise tolerances, and robust protection for your drive train.

• Brass Oldham coupling with CNC precision for minimal connection gap and low inertial movement
• 8 mm lead screw compatibility; center distance 18 mm; M3 fixing holes
• High torsional stiffness to guard driven parts and support bearings against radial misalignment
• Mitigates print quality issues caused by heat bed swing and slight lead-screw misalignment
• Designed for 8 mm lead screws in T8 systems
• Compatible with CR-10, CR-10S Pro, Ender-3, Ender 3 S1, Ender 3 Pro, Ender 3 V2, Ender 3 Neo series, and other printers with M3 fixing holes and an 18 mm hole spacing
