Passive Income Idea (Sell STL Files)

One industry that is in demand is 3D printing. All 3D printers use STL or OBJ files to print out there object, being able to design these files can be a great business to get into. You can earn royalties and sell or license them anyway you’d like to. All you need is a 3D rendering software (Blender or Adobe) some are free but if you are serious about doing this then purchasing a subscription to a more advanced software will pay off. STL files can earn up to $500 each and you can sell them anywhere online (website / Etsy / Cults3D). Some good industries that use STL files are Cosplay / Aerospace / Automotive / Fashion and Medical.
