I have printed several airplanes from T-verse but always had a hard time with the wings, especially at smaller scales. If wings are modeled to scale, they are too thin to print. I modeled this with chunky wings to keep them printable at small scales.
I recommend using the "printable" file, and making 2 or 3 at a time to allow cooling between parts. Printing without supports works fine if you use enough walls (4 for me) and high resolution (examples were 0.1mm).
This is the same scale as most Daron model jets.
