Hi team! I've placed the project file for the Geo Nodes tutorial into the downloads folder for this month. Remember, this file will only work with Blender 2.92 alpha, which you can find on the experimental builds download page at blender.org
If you are a All-Access Patron or higher this month (December 2020) you'll have received a direct message with a download link.
