Box exterior itself is approx 60mm x 60mm x 50mm without lid (approx 70 with lid) The bow and decoration are separate files just in case you only want the box. I deliberately made the lid not flush fitting to make it easier to open. All items scaled well when I tried printing a larger version. Box was printed with 15% infill and ironing was enabled.

The decorations were printed with supports, as was the bow. All were printed with a raft as the scribble tree is a bit delicate.

I've edited to add the box and lid as separate files, so now you can print them separately and scale them, just make sure to scale them to the same size.

This is my first foray into design, so feedback would be appreciated
