Modular storage systems?

I'm currently working on decluttering, and coming up with processes to stop clutter from building up in the future.

Even after getting rid of a bunch of junk, I'll be left with a ton of stuff that historically has just "floated around" my living space (cables, adapters, small tools, stationary, batteries, etc...).

I'd ideally want a bunch of appropriately sized containers that I can organize stuff into. I'd love for each box to be some tesselation of a standard volume, so that I can arrange and stack those containers neatly in a drawer or on a desk.

If you happen to work with 3D printing, this may sound a lot like Gridfinity, a modular open-source grid storage system. And I agree! Gridfinity's goals completely meet and shoot past what I'm looking for. But I currently have no interest in investing the money or time into buying a 3D printer and making prints. And there doesn't appear to be an obvious commercial version outside of "random" folks on Etsy.

I also considered getting a Drawer Grid like you'd see in a Maker Space. I might end up getting this if I can't find a better option, though I'd prefer a storage solution I can stuff in a drawer.

I was curious if:

• Anyone had any product recommendations that might fit the bill
• Anyone had any thoughts on the organizational endeavor itself, and if there are any ways I could be going about this better.
