About this 3D model

Removed both turrets and added a separate one that can be attached as desired. It prints just fine, but I will upload a new file soon with stand alone wheels, as those seem to print kind of crappy with a bunch of hard to remove supports Also for attribution this model was made by a user called "IDW01" in the sketchup warehouse. Here is his deviant art page : http://idw01.deviantart.com/. Waiting to hear back about usage permission. If anyone has any ideas on how to contact the owner (aside from his deviant art profile), please let me know.
