I just wanted to say that I absolutely love these. Hex anything is really nice from a design point of view. I strapped 24 large HexCans and 6 small cans on a hex probe core and shot it into space.. It looks so nice. Took a huge rocket to get up but its so pretty in orbit. I love the surface space, I put all of the science equip as well as the MechJeb and Engineer computers neatly around the outside. There is no way I could have made this compact of a 'probe' as huge as it is without these HexCans.. love em. It still had a good amount of supplies on board but it was really heavy. I am going to be using them as small fuel storage caches in orbits everywhere. I wanted to second the notion of these containing IntakeAir, I soo need air containers to power my H.O.M.E generator on airless worlds.. and I figure shipping in air should be lighter than fuel, and more fun to set up the generator base. Also SM pulse engines use Compressed Air which can be made from IntakeAir or there could be a HexCan for Compressed Air as well eventually. I plan on just doing the config edits for these parts myself but I really think they could be in the mod, good resources. One last idea, I really like flat edged designs and I think an adapter to THSS tri-hexagonal strut would be a really great fit. Since you both are non quad. Can't wait for the updates.
