Enerjet by Aerotech Strong Arm Build, Part 4, Strakes

On the left is the front of the strake, on the right is the rear.

The final tip cuts are marked with pencil.

Cut them a little wide outside the pencil lines. Then sand to shape with a block.

TIP: It's easier to visualize the shape by turning over the strake and checking the bottom.

I drew a centerline to better see the wedge shape.
