Step 1: Cutting three lengths from a piece of cardboard tubing
Cut three equal lengths each about 4 inches long from a piece of salvaged cardboard tubing using a saw / hacksaw.
Now bevel one end of each piece by removing a small piece of tubing. Finish the pieces by smoothing down the rough edges using fine sand / emery paper.
Place the three cut and finished pieces of tubes on a flat surface, and align the edges so that a triangle is formed in the center. When satisfied with the symmetry, use a couple of rubber bands to hold the three pieces together. Number the pieces 1,2 & 3 and run a pencil up and down in the grooves between them.
