This free course only uses a single dataset as well as a downloadable shortcut sheet. You can use any of your own models to follow along with the videos. If you want to play around with the rim you see in the videos be sure to download the dataset folder. If you want to learn how to model the rim we have an entire YouTube Series on that process which you can find here. https://www.youtube.com/playlist?list=PLBDfGh8A8kXUcqeGKo3KYer-ENfAnfT2g
