Hey weinzierl, I'm a CAD modelere/mechanical designer who wanted to learn Blender. I highly recommend https://www.blenderbros.com/products/hard-surface-modeling-jumpstart https://www.blenderbros.com/products/hard-surface-modeling-j... . It was outstanding for me. It showed me many, many ways to speed up the Blender modeling workflow, and it's about shapes/types of things that I actually want to make, unlike a donut.
