With 3d printers becoming much accessible selling 3d files is a popular avenue for creators as a means to support their hobby while still providing a product.
Foam is still largely popular but the the files (made from game rips) are free of charge due to non commercial files being used. Unfolding also takes a decent amount of time for the person doing it.
Be the change you want to see! Pulling your own files and learning to unfold them is beneficial not only for yourself but the community at large
