Needle alignment setup

Hi

I am looking for help and ideas on how to build a very simple alignment setup. I have a small needle which I use to produce small droplets of water that fall onto a surface directly below it. There are a few main features I need solving:

1: Course adjustment of the needle height (around 2cm per step) over 1.5m
2: Fine adjustment of the needle position in the horizontal plane (1mm per step) over 5cm

I have added a very rough sketch but any ideas are welcome thank you for the help.
