A red, white, and blue rocket. Everything presses together, but glue might not be a bad idea. Make sure you assemble the rocket body so that the three fins end up equally spaced around the model.

The pegs for the main body need to have the brim trimmed off and are a little tight.

The star may require a bit of force especially if you don't trim the brim well.

If you try to modify this pay attention to the fins. There is a negative element in the 3MF to trim the corners. If you remove it the fins won't fit.
