LED flashing xmas tree

Christmas tree for 5mm LEDs, I am planning on running this with an arduino nano. Hopefully I actually get around to comleting it. I have test printed it and the LEDs I have fit perfectly in the holes, no glue etc. needed. Pot, and toppper hold the two halves together, I think a little blob of glue may be wanted on the topper.

You will need to print the main xmas tree body twice.
