The proliferation of 3D printers probably had a negative impact on the sales of Altoids

You used to see Altoids tins used for project boxes for everything imaginable, but since 3D printers became widespread, it's extremely rare to see the tins used for projects anymore. I know a a lot of people in the makerspace who would only buy Altoids to use the tins afterward for their projects. Now, they just 3D print a custom case.
