The standard 3Drag z-axis endstop is pretty inacurate. Just by moving the screw a little to the side, you'll change it's angle and screw up the z zero position - kind of literally.
This improved endstop screw holder let's you place two nuts in a straight line, holding the screw perfectly vertical. You can also use one ordinary nut + one nylon locknut. The locknut will keep the position more stable. A second locknut placed at the end of the screw will increase the area hitting the switch - making a miss impossible.
I was able to decrease the time I spend for printer maintenance & calibration significantly. So I thought, I'd share this little improvement with you!
