Make sure your end cap is flushed against the shell and is next to the slit marked in image 1. Pull any slack from behind the end cap so it's a comfortable length without it being too taut.
Also make sure the acrylic is oriented as shown in image 1 with wires coming from bottom.
Hold that end cap piece at its designated length and drag along the circular pieces to it. Make sure it is concentric.
Acrylic cement the pieces together.
