#Lego is lightweight enough that one could go the #ReallyUsefulBox route, I suppose.
There's a lot of volume lost, and one doesn't get the small sizes of a 1/8th third-party subdivided #StanleyFatMax bin. But the gain, on the other hand, is that the inner #boxes are not only stackable outwith the main container but _also_ have secure lids even when stacked standalone.
I have put more effort into this than I expected to from an offhand comment. (-:

The #StanleyFatMax replacement bins aren't stackable, though. I notice in the video that xe talks about the bins being rearrangeable. For the FatMax, they are _also_ in fact designed to be stackable, outwith the organizer on top of one another, possibly useful for #Lego.
That's what the little tongues and grooves are actually for. The 3-D printed substitutes have them, but the added dividers get in the way and defeat the design.
If one is going to take this this seriously, and it appears that people _do_, then I'd go with a #StanleyFatMax organizer over a Sortmaster.
Both have removable bins, but the advantage of the FatMax is that there are people in the U.K. that 3D-print substitute bins that are subdivided into 1/3rds, 1/4rs, and even 1/8ths, useful for those smaller pieces where an entire bin, even one of the small ones, is a waste.
