Before you turn your 3D printer farm dreams into reality, it is worth slowing down and thinking through what selling your 3D prints entails. It is more than uploading a few photos and waiting for money to appear in your account. You are taking on legal responsibilities, quality expectations, and basic business logistics, even if it is “just a side hustle.” If you get the foundations right now, you will save yourself a lot of stress, reprints, and awkward conversations later.
