Like, you don't really need that complex of a setup. This requires several points to be core-adjacent rather than just one, but it is more compact. Also no overdrive. If you wanted to include a switch, something that just changes the unloaders from unset to something that isn't used, like sand, would be able to cut off supply. You could also, of course, change it manually.

Not exactly the most compact, unless you just mean the smallest rectangle that fits around it.

@Dr Mitchy Here's something:

It's from the previous version, so the vaults aren't lined up so that you can also fit two containers, but you can easily modify it or just leave out the core/vault portion.

vaults on core work well

seems good but could have some problem with needing to be put on a core got any other versions?

Works well, thanks! Is it possible to use something like this on a container instead of a core?
