So there is a lot of Lego and it's time to sort it. All up there is maybe 1/2 a typical red lidded garbage bin worth, which is very heavy all up. I know I'll need two or four large plastic tubs for just regular bricks and flat bricks, this makes up the bulk of the lego and doesn't need to be in special little drawers or anything. But I'll also need somewhere for two lunchboxes size worth of wheels, and four lunchbox sizes worth of windows/doors. Even the minifig heads alone are the volume of a few oranges.
I'd like to put all those things in little drawer compartments. Requirement is that the drawers can't be fully removed and all dumped out, so they need to be deep enough to rummage through. So I guess wide and flat drawers would be ideal, so they can be spread out in the drawer itself. But i just want it to be hard to mix up again, anyone using it should be forced to pick and choose from the drawer itself.
I've looked at some tool organisation things on eBay and Amazon and they look fine, but they are too small. I need big but compact storage that kids can safely use. And it doesn't need to hold all the lego, i can take some of the heads and wheels out of rotation, for example, because no kid will need 150 wheels at the same time.
I can see all the professional lego storage that is sold but that seems like a lot of money for something that is basically just a little plastic set of drawers.
IKEA has a huge range of these kind of things.
