Thanks for those boxes! They are very handy!
They print easily;
My Tie Phantom was too long to fit in the box; after investigation it is clear that the manufacturing of the ship is the issue: the left wing was glued in incorrect position, ca. 1 mm, resulting in a longer ship than expected.
I used some big metal paper clips for the hinges, worked fine, easy to cut, just paid attention to file the ends so that it is safe for my boy :-)
I still have issues with the lid for the Slave I, it is much bigger and I experience warping issues, hence the hinges do not work. Will try again later...
