18650 holder configurable

This is a 18650 holder I drew up in OpenScad. It isn't a very dense version, but it allows for easier replacing of cells and stacking using holes and threaded rod.

You route a solid copper wire through the guidance holes and solder fuse wire to the cells from there.

You can configure half open or not with a true/false. It only makes sense on the 2 by x configuration though.
