I don't understand the sibling posts that're arguing with you.
Consumer-grade containers would be cheaper than 3d printing if buying a set, it'd get folk up-and-running without fuss, and when they wanted to customize it they could do so with the help of any of their 3d printing fanatic buddies.
So yeah. I agree with @stephenpetryk. Storage solution companies should start marking their bins as Gridfinity-compatible (which is a protected use of copyright regardless of whether "Gridfinity" is copyrighted).
The place to start would be enough basic bins and the grid itself for the Alex drawers from Ikea.
The cool things about gridfinity is not just the custom pieces, but also the exact fit that can be achieved. Since every drawer seems to be a slightly different size, exact fits with basic bins would never quite be achieved without targeting a specific drawer.
Also, I've turned down the fill and structural strength a lot without issues for most things. How strong does a bin for cotton swabs need to be?
