I made these to make the level adjustment easier and included the factory file so you can just download and print if you have S3D.
Or just print the gcode.
Support is included in the files.
Or single part STL is included.
Printed "UP" on the top surface makes adjustment easier as you don't need to think which way to turn the knob.
You will notice in my Factory file I print a large offset skirt 3 thick so I have plenty of time to fine tune the Z height/levels before the print itself actually starts.
I have included the Fusion 360 file if anyone wants to modify anything.
