My colleague at work is a very talented 3D Artist. She and her team have put together this amazing "3D Model Prep Masterclass" tutorial and I'd love to share it with you all.
I think it demonstrates a good mechanical use case, and would love to get it to people who will enjoy and benefit from it.
I'll leave the link here: https://www.jig.space/tutorials/jigspace-3d-model-preparation
If you have any feedback or comments, I'll be sure to pass them on.
