I have loads of those stackable IKEA Glis boxes. But I also have loads of small hobby parts. 

Heres a set of many variations of subdivers that simply slot into the Glis boxes.

I recommend printing the large parts with high bed temp and brim to avoid detaching mid-print. The bottom does not need to be pretty due to the chamfer insert so brim is well okay here.
