MK4/MK3.9 printable parts

Finished my Mk3.9 upgrade. Had a little issue with the Z calibration and seem to be past that. The print quality is fabulous! All the printed parts came out great so kudos to the people that sliced the files. I went with Ultramarine Blue for the upgrade. Hoping for another 5 years of printing since I replaced the rods and bearings too.

@fscats_78466 In my case the z calibration failed on the initial self test and continued to fail multiple times. What I did to apparently fix this is loosen the screws holding the z motors by about a quarter turn. This allowed the z calibration to be successful and continue work. I haven't had any issues since. Also, the print quality is great. Even printed ABS with no issues. I hope that you are able to fix your issue as the Prusa fixes didn't work for me.

@Docbadger_15249 what did you do to address your z calibration issue? I have an issue where the z calibration worked as part of initial self test, and my first print worked fine, but then my z calibration reset to 20 mm above the bed. If I do a factory reset and complete self test it will work for a print and then have the same problem.
