You could use the "Create new Image" model in Layout and insert a picture of your snowflake then copy paste 11 times. String Type = Single Colour
Then make a Group of all 12
Or you could use the attached model I just made (it's a bit rough, use it as a guide, you will want to make it reasonable size in layout to see it properly, you may also want to add spaces between Xs)
You can turn all on at model, or it has 3 vertical sub-buffers for turning on all stars in each of the 3 columns or you can expand X1 submodel to see each of the 12 nodes (snowflakes) to turn each one on separately as required.
