Z Height Comparator / level / gauge

I made this for the A6, may work with other models as long as there is room to get the gauge under the x axis rails.

I wanted something adjustable i could use for making sure my Z was level in the home position. been using a small glue stick which was just a bit short then eyeballing it. The version I made had full threads in the body and lock, and was a challenge to get together the first time. The file here i took a lot of the unnecessary threads out, it should make it go together easier without losing any function.
