Thanks! I do have a lot on jewelry and 3D printing, but I also recently launched a purely introductory course which is for anyone interested in Blender. Just visit my Skillshare profile page, there you can find all the courses if you scroll down, as well:

I skimmed through the course and will do the tutorial later on my machine.
The combination with jewelry is nice even if I didn't know such use-cases exist.
