Sidewinder

Most pilots start their careers in the Sidewinder. It is a classic ship design that has been in use (in various configurations) since 2982. Its original design was as a light support ship and it lacked jump capability. Modern compact drives have enabled jump-capable versions to be created, making this a useful all rounder. Some navies still use these ships as fighters and patrol craft.

If 3D printing, you might want to print the main hull and the engines separately to minimize supports.
