I think I'll keep using this thread. I learned how to show the keys typed in blender so I can start building basic tutorials.

Here is a super fast tutorial on how to make the jagged star I posted under Holiday and Seasonal. Still experimenting with videos so not very advanced or professional but the tutorial shows how easy it is to make this pattern using blender and modifiers. As an alternate do the same without the modifier.

I did not show exporting as stl because its pretty self explanatory. Ensure under user preference stl export check box is checked and then on the main screen select export and then from the sub menu select stl.
