Yours is a very nice thought. Don't give up.

I'm thinking about a business working not local but global: There are a lot of plastic parts in the products we use. They wear out over time. In fact, since the very old products are no longer produced, spare parts cannot be found. Some products are used far away from the countries where they are produced. Parts logistics are always a problem.

I'm thinking of an archive of 3D printable spare parts files website that grows over time. Everyone can contribute. But only bitcoin will be used for the sale.
