Clamshell armored siege tank [FDM FRIENDLY]

This project was born from 2 ideas. First of all, to create an armored artillery vehicule whose canon can be moved up or down. the second idea is to allow printing in a minimum of parts, by proposing a design with only 2 elements for the hull: a top part and a bottom part, like a shell. As all my other projet, this one is FDM friendly. Can be armed with an howitzer, a tank canon, a long canon for an artillery or tank hunter design, or quand flak canons.
