The file 'Z Coupler V2 For M4 Set Screws, No Z Wobble! 3D Printer Model' is (stl) file type, size is 107.2KB.
A better 8mm Z rod to NEMA-17 motor coupler. Reliable, accurate, if installed correctly, elliminates Z-wobble and requires only 12 M4 set-screws. I use it on my DIY printer on which the Z motor is on top of the rod and the coupler holds the weight of the gantry. 1 kg of prints later and still holds up perfectly.
