Brain Slug V2 (clean/simple geometry and flat bottom)

I was in need of a brain slug to improve the classiness of my hard hat for this upcoming weekend. Originally I just indeed to clean up the geometry in 7777773's original. I was having a good day so I just rolled with a redraw. Then it was now and then I don't know what happened.

I made it an easy print by keeping the geometry solid and the bottom flat. The antennae are intended to be bent with a heat gun so I could make them easier to print. Don't forget to bend them; they look awful straight up.

You can adjust the polygon count in the scad ($fn) if you desire more or less.
