The original design had the star mounting inside the stud on the individual wreath branch, which isn't really keeping in spirit with the way this wreath would be constructed in actual Lego. Resizing it produces a stud on the top of the star which is too large. Also, while I like the way the bottom stud tapers into the star shape, the thickness of the whole part becomes too much.

I deconstructed the top stud, star and bottom stud hole from the original and recombined them in the proper size so the bottom hole would mount on the matching 30 mm stud found on the wreath branch and provide a 30 mm stud with the logo on top.

I removed the taper between the stud hole and star and just made the part flat. 

Support is definitely required to print this new decoration.

The bottom hole may still be a little too loose to mount on the wreath branch so a slight scaling adjustment may be necessary depending on your printer's tolerances.
