🔧 Elevate Your 3D Printing Game!
This 2PCS Coupler Flexible Couplings set is engineered for NEMA 17 stepper motors, accommodating shaft diameters from 5mm to 8mm. Made from high-quality aluminum alloy, these couplers ensure robust performance and compatibility with a variety of 3D printers and CNC machines, including popular models like Kobra and Ender. With a compact size and a value pack of two, they are the perfect addition to any maker's toolkit.

Good Flexible Coupler
I used this to upgrade my Voxelab Aquila (Ender 3 clone) to a flexible Z axis coupler.The two grub screw system holds both the lead screw and the stepper motor shaft securely.The only potential "gotcha" is that the internal length of the coupler for the stepper motor shaft is *very* short. Use care when mounting the coupler, and avoid putting too much of the shaft into the coupler; only seat the shaft to the point at which the internal sizing of the coupler switches from 5mm to 8mm (the top of the narrowest part of the internal opening). If you insert the stepper motor too far, you will NOT get the full benefit of the flexible coupling!Good part at a very good price.

They add spring to my...shaft
Flexible couplings. What can one man say about flexible couplings. What generous words does the English language offer to show respect and humility towards the mighty flexible couplings? Some would say, "they work as expected."

Work great
Works great I would suggest getting a couple 6mm ball bearings to put between the stepper and the lead scew to prevent compression

Unusable
I used these in a dual Z asis kit ant they simply should not be used. I set my new Z and leveled the bed and that is when my issues began. Ther very first print showed these couplings are no good for a 3d printer. The print failed as the Z asis did not maintain the same height.
