There are very few items that people want to buy and use that are 3D printable.
i.e. 3D printers cannot make good plastic bowels (yet)

That store front had basically two kinds of items. Swag (printed merch) or easy to make decorative items.

What we need is everything you would find at Wallymart.

And i have a CNC mill, so i can make all the stuff that i want.
But this isn't about making a one off, it is about creating an industry.
