3DLabPrint Spitfire XVI Exhaust Stacks

Having just printed a 3DLabPrint Spitfire XVI, I felt something was missing: The classic Spitfire exhaust stacks; so I made some. On the Starboard side 3DlabPrint have placed their logo just where the exhaust would go. Therefore there are two models: the standard one and a stepped one which fits over the logo. The stepped model has support modelled in so you don't have to add any.
