This is an improved remix building off the the Atomstack Z-Axis Screw for an A5 and a combination of other various Air-Assist ideas.
The Z-Axis Screw Knob Thing this was remixed from was missing a 10mm Base to stand it off the frame to allow it to retain and use the M50 Laser Module Guide and the original Z-Axis screw base needed to have an Air-Assist nozzle added to it.
I have included all necessary files here for the complete setup, all that is needed is the 2mm Brass Tubing, link to Amazon is below.
The companion Remixed Thing to this is the Air Assist Nozzle here https://www.thingiverse.com/thing:4741591, and a short piece of 2mm Brass tubing found here: https://www.amazon.com/gp/product/B09B8NXBRS
