Hi, On my ultimaker the Z-guide metal bar is too close to the wall of the ultimaker to slide this component into place.
loosening up the side and using some force got it in.
maybe the both sliding guides could be somewhat shorter.
Anyhow, it works.
Setting the Z-Axis is now very easy !
Thanks Gijs

I would also suggest to add a spring from a ball pen between the adjuster and the UM plywood, so make sure that adjusting it keeps it in the right spot.

This worked brilliantly for me with a couple of tweaks. I added a heavy spring around the top bolt and i snapped off the little legs so it can be fitted without removing the z-rod. The screws from the back that secure the switch are more than enough to keep it from twisting.
