Greetings Starfighter! You have [once again, but this time in higher detail] been recruited by the Star League to defend the Frontier against Xur and the Ko-Dan armada. Get ready! Prepare for blast-off.
This is an Hi Poly version of the Gunstar from The Last Starfighter, which I guess makes the previous model a beta unit.... And that brings us to Lesson Number Two... You've got a good thing going here. Keep smiling, don't blow it.
The single-piece print will obviously require a bunch of support, regardless of orientation.
The split files should print OK without support but there are a few areas with overhangs that could use it to print perfectly.
