Gun drone Shortstack v5

So like many people that play Tau in 40K, I have a lot of the extra bits for them laying around in boxes. So, I decided to make a slight variant of a gun drone, that still requires the weapons from the 40K kit and maintains most of the aesthetic, but is a little different.
The initial concept was simply for a gun drone that had a sort of clam-shell function, so that it could be more easily stacked for mass transit and deployment. Theoretically, the weapons and such would be intended to be able to collapse down inside and the outer shell could close.

I've been through a few versions building and improving this, and it should mostly work just fine at this point. I built them with the weapons from the standard gun drone kit but with the back of the weapon after the connector point cut off. Also with the underbarrel launchers cut off to save space, and because it looked odd on this, and the grenades basically dont exist as part of the carbine anymore.
