It seems like the actual version of Fusion has problems with projections inside some sketches.
This problem is definitively new since one of the last updates. At the moment I don't have the time to re-construct it. But hopefully it will work after the next update of fusion again.
In a few weeks I can try to re-design it, but at the moment I don't have time for that.

I uploaded many different sizes, but you can also make your own size using the uploaded "parametric Gift Box.f3d".
You need Autodesk Fusion 360 to set the parameters. It's free for private use.
For those who are not familiar with Fusion here are very detailed instructions (see also the uploaded screenshots):
Open the file Parametric Gift Box.f3d in Fusion 360.
Repeat steps 4-8 for all four parts (box, lid, ribbon, ribbon_bow)!
I used PLA with .2mm layer height.
If you have any hints or suggestions please let me know.
I would love to see photos of your gift boxes …
