Z Axis guide
thingiverse
This is a number guide for the Z Axis on an Ender 3 or 3+. it should work for any 2040 extrusion. I wanted a visual guide of my X gantry to see if it was level. it is not 100% but it will give you an idea. feel free to modify and upload. you will need to print it with the numbers facing up and support on the underside. us a change filament at layer height to change to a different color.
