Reply To: Z-Nut Lock



The coupling nut measures 12.73mm, the regular nut I have is 12.75, and the lock nuts I have been using 12.80.
The coupling nut is 25.85mm long

I printed both Z-Nut Lock, both have a step inside that prevent the coupling nut to slide all the way in. Or am I doing something wrong?

Should I print the international version since I am using metric all thread?
