thingverse and their printing partners do that. you can buy most designs. But 99.999% of the models there are complete garbage that people print when they force themselves to use the printer they have no use for.
I have some that are fully parametrized (done in openSCAD) so that the buyer have sliders to adjust whatever they want before purchase. But all the time people just "remix" my design (after downloading the non-parametrized STL file) and print themselves, which is fine (designs are all gpl3/c-left)
All that said, i personally think doing artisanal-volume items with plastic is completely wrong. Plastic have no advantage over wood. None. zero. save from being a commodity that won't halt your factory production while you wait for the right wood in large quantities, which do halt factories very often.
If you don't run a factory non-stop, don't use high-volume methods like continuous extrusion, have no need for soft materials like silicon or things full of infinite holes... a 3axis mill and wood is a much better choice for quality. Not even considering the green arguments whatsoever.
