Not at all suitable for FDM 3d printing without major modification. Perhaps would be viable on an SLA (resin) printer, but I feel like even that would require bringing the model into a 3d program to make some modifications. Its a decent model, but just be prepared to put in some work to get a good print out of it. A few improvements that could be made: - Separate each part into its own STL. Having one mesh for each individual part would make this much more convenient to work with in a slicer. - Key the 2 halves of the main hull so that gluing is easier and more precise - Fix the wing attachments. The ball and socket for the wings is not sized well, it is too loose and would need to be glued statically in place rather than left as a friction joint that can be articulated - Increase the scale. The model is extremely small when imported directly into a slicer... had to increase scale by 400% just to get something that my FDM would have a chance at printing at all
