Rotate vessels in their center

Right now vessels rotate in a not so symmetrical way when attempting to place them.

This behaviour is due to the fact that the origin/pivot of the 3D Mesh (0,0,0) is located in the wrong spot.
For example, the MizbeachHazahav or Shulchan correctly have their origin in the bottom center of the mesh. This not true for the Keresh, which has its origin located at the bottom of one of the pegs. This causes it to not appear in the center of the screen, nor rotate in its center.

Solution: In Blender make sure the Origin of the mesh is in the center of the mesh.
