Some of the new guys at work where having issues keeping track of the the cnc mill axis,
So I made a sign for them that shows the axis directions for a quick reference.
I mounted this one to the top of the Z axis on my Haas mill.
I just used some 2-sided tape on the back to attach it.
Files have both MMU and Single color print files and the letters and icons are raised so its easy to paint them if you dont have MMU.
I printed it in PLA and it worked fine,
Easy to print no special settings.
Printed with both my MK3 and MK2 printers and the both had no issues with it.
