Coronavirus panel: extract outlines

I’ve been trying to generate a panel with a random Coronavirus like pattern for cutting out with a laser.
All is well until I get to trying to extract the outline of the shapes for the laser cut path where I am stuck.
I’ve tried with solid union - brep edges, and also curve intersection - shatter, but so far no success.
Any help would be great!
