Blinking Christmas tree

It's a small christmas tree with blinking lights to decorate your table with.

For about $1 worth of components, you can have a merry table decoration that you can show off your 3D printing and electronics prowess with this year.

The tree has 16 holes for 5mm LEDs, room for the circuit and battery inside, with a switch in the base

Circuit design is included.

edit: Fixed some overhang issues and made holes a little bit bigger to more easily accommoate 5mm LEDs
