Subject: [OpenSCAD] 3D five point star
One of my projects has a star in the center. Using the “star” BOSL2
routine then linear extrude to produce a 3D object works but it looks
plain, i.e. flat on top. Any suggestions how to get something like the
pic below.
Thanks, Mike

I thought you wanted a flat back. If not instead of $fn=3, make it
$fn=4, maybe need to rotate it, and omit the intersection. You can alter
the 'thickness', by using scale on the point in the appropriate direction.
