Collider on Bone changes Bone Origin/Pivot

Questions & Answers
1

I am making a very simple tank vehicle and have rigged it up in Cinema 4D R14.042 with 3 bones.
C4D TankRig

I have added it to my unity project and everything imports correctly. Since the colliders need to move when the turret and barrel move, I have attached a box collider to the body, turret, and barrel bone. This in turn changes the origin of movement for my turret so when I rotate it it does not correctly rotate about the turret middle (see image)

How do I get colliders that move with the bones/mesh but also maintain there original origins so that programmatic animation is correct?

Edit:
The selected answer was the solution but I have just come across this great video on creating custom pivots and thought I would share: CG Cookie | Learn Blender, Online Tutorials and Help - CG Cookie | Learn Blender, Online Tutorials and Feedback

Hello,

Top left of your screen you can see a pivot button. This changes the pivot in Unity from the centre of the object (calculated from colliders) or the position of the object.

Hope this helps,
