2005 Dalek front curved slat

This is the slat 1 curved front piece from my collection of full size Dalek parts (2005), I haven't printed it yet so I can't advise on the supports or suggested layout, I can say that the sphere's project through the back and will need removing, I cant seem to do this on Inventor without ruining the whole sphere. Maybe print facing up, with supports underneath and remove the whole lot.
Fortunately you will only need one of these so its not too much hard work, the next slats, 4 no will be added
