Patreon is a membership platform that allows artists and other creators to provide their works to their followers through a subscription service. In my case, I provide the STL files (the 3D printable files) of my 3D models to my Patrons who support me on Patreon. In this way, I get a certain amount of money each month for the creation of my models, while my Patrons can 3D print my designs at home.
