Spitfire (e) for FDM Printers

This is a 20% scale remix of the RC Spitifre project of @MustangDave
The minor changes to the model include a radiator, oil cooler, prop spinner, and tailwheel. A set of landing gear is also provided.
This model can represent either a Spitfire Mk. Ia, Mk. IIa, or the very rare Mk. Va.
Update 31 Oct: Added FDM model without main landing gear.
Update 1 Nov: Added improved (Mk. II) FDM model due to problems with the original FDM model.
Update 4 Nov: Added further improved (Mk. III) FDM model (Scale up to 200% in slicer for the full model, some parts are very thin)
Note 17 Nov: I am still trying to find a way to thicken the parts for micro-scale printing. If you have advice, please comment.
Update 17 Nov: Added improved model with accurate tailwheel and no gap in the starboard wing. ("Spitfire Mk.IA/IIA Standard" model)
Update 18 Nov: Added new model with thickened wings and control surfaces (finally!) after learning the process via Google.
