Here's something that I wished existed. After getting a 3D printer, and learning modeling software, I'm constantly creating "stuff" that doesn't exist in any store, but satisfy needs I've had around the house. Now there are 3D model hosting sites where you can sell downloads of your model file. And there are 3D printing farms where you can have them crank out and ship you any quantity of your models. I want that combined into one B2B entity where I can place a listing for one of my products on something like Ebay or Amazon. Then when a customer orders it, have it fulfilled by the 3D print farm company, package it up with my product instructions, and ship it out to the customer (and once volume hits a certain level, maintain inventory at Amazon for example). They collect payment and send me the difference between my sell price and their manufacturing price, with automatic price breaks when volume hits a specific level.

Objects that I've designed and 3D printed for myself include things like Dremel tool attachments, dust port attachments for my router table, nut/washer holders that you screw on the bottom of a table to hold the nut in place (so you can move a top post from one location to another as needed without reaching under the table to hold onto the nut), things like that. Some small items, some larger mechanical devices.

The closest I've seen to this is some woodworkers on Youtube run their own store and have a small number of 3D printers for cranking out the products they sell. I want something like this scaled up for any designer.

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.

This is a legit good idea. I would use this. There's a huge variety of things that would fit this category.
You may already know, but Slant 3D (print farm) do _some_ of this with Etsy and Shopify, and have an API for further integrations.

(I am working on a product myself, but it would likely have assembly needs beyond what Slant 3D do, and at any rate I am not in the USA)

How do you research and evaluate different manufacturing and assembly options? Is that difficult and something AI could perhaps help with?
That's a great idea - interesting to see Slant 3D in this space! What do you make of their offering?
