A while back, I started making tutorials (for Latin American Community, so in Spanish) specifically for Jewellery Design for 3D Print using Blender. I have created 27 of them so far. Even if it’s in spanish, I have followers from many places. These tutorials are generally long and complete, from scratch to the final render, creating the entire design during the tutorial. I hope they can be of use to many more people.
Enjoy!
