A Christmas tree made of Koch Snowflakes (iteration 3).
To print out the tree, print the following files:
My Cura settings are in the JPEG. I used 20% fill.
When you assemble the tree, be aware that the holes in each layer have the same taper as the trunk. So the layers fit much better one way up than the other. In fact, they should sort of click into place because of the matching tapers.
If you want to play about with the Koch Snowflakes, I have also uploaded the DXF and SCAD files. For instructions see the featured thing http://www.thingiverse.com/thing:35246
