This is an updated version of my ExtraFast Profile (0.28 layer height) for Cura version 5.0+. with added .stl file. Instructions:

Download the .3mf and open it as a project in Cura V5.0. Select "Create New" for the Printer Settings so it doesn't override your existing Machine Profile (you can delete this later). Select "Create New" for the Profile Setting to get the new V5.0 Best profile. The model is a test print to verify the profile is working on your machine. Slice the print and run it on your Creality Machine. Note: If you don't have a Creality machine, use the included machine profile and adjust it to match your printer dimensions and rename it. This will give you access to all my future profiles.

I've also added the .curaprofile for those who cannot load the .3mf
