UGears - Butterfly, 3D mechanical model

Use traverse and elevation mechanisms to set a required angle in horizontal and vertical panels to ensure the best aim. The lever of winding mechanism on the right side of Archballista functions as a trigger to launch bots at the target when the aiming is set. The firing part of this module is detachable, and can also be installed on the top of the Tower. 
Few intriguing construction features are hidden under the delicately ornamented tower. The gear on a side of the tower activates the raising/lowering mechanism that extends the tower to the second level revealing a spiral staircase and interior structure.

This model is unique because it can be used as a single module to reenact medieval siege games and as a two-piece in multiple-player artillery battle when the Archballista charges against the Tower.
