A minor tweak to @paulvdh approach…
In the Footprint editor on a new footprint):
- Draw a section of it using the Graphic Polygon tool (draw segments of the Curve)
- Right-Click it, Array (set H & V 2,1)
- Window-Box them, Copy, Rotate, Mirror
- Double-Click each and change layers as desired
- Add 4 Pads, Double-Click, change to SMD. One over each section
- Window-Box one section (to select it) Right-Click, Make Pad From Shape. Repeat for each one
- Draw a Silk circle around it
~Done~
