I'm getting a bigger band saw, & so working on the far corner of the shop, where the least functional stuff drifts to, including the two systainers mentioned upthread.

I measured the one that has the domino assortment- the actual space holding the parts is 532 CI, and the overall box is 1184 CI, for a 44% efficiency.

If they go in cut off milk cartons, they fit with an additional empty carton in a box 790 CI- I think I'll do that.
