Z-coupler 5-8 mm

This is a z-kobler for a standard stepper rod to a threaded rod. It takes a M3 bolt in the side for hold it tight, as shown in the last picture.

What i did, was to smelt a M3 nut unto the plastic for the bolt to go into. i just used a solderingion to heat up the nut and push it gently into the plastic while holding on to the coupler with a par of pliers.

Please let me know if you make one and feel free to leave a comment if i shold change something, that really helps me out
