In order to create the free standing Christmas tree with separation you need some separators. In my case I made the separators from two 2mm diameter ferrules soldered back to back on the same axis with wire. In order for the ferrules to fit in the centre of the snowflakes a 2mm hole is drilled in the centre as a small hole already exists in the design it makes it easier to align in the centre for drilling. 8 separators are required to build the this variant of the Christmas tree.
