PiClop cam tower split for smaller print beds

Cura didn't let me slice the cam_tower STL off FaanP's thing, since it was too large for the print volume I set up for my geeetech i3 (20x20x20), and I didn't want to risk printing such a big part anyway by enlarging the print area in the settings and just see what happened.
Hence I played some boolean magic with a plane object in Blender (the only 3d modeling software I know how to use, kind of) to split the tower, with the intention of glueing the pieces together afterwards.
