A flexible mold for a smoking device having a cup-shaped outer wall, a cup-shaped inner wall, and a third cup-shaped wall. The outer wall has a continuous sidewall connected to a bottom wall containing a central opening. The sidewall of the outer wall extends from the bottom wall of the outer wall to an open end and contains an opening in the sidewall spaced between the bottom end and the open end. The inner wall has a continuous sidewall, a cover closing one end. The sidewall of the inner wall is attached to the bottom wall of the outer wall surrounding the central opening. The third wall has a continuous sidewall and a closed end. The sidewall of the third wall is connected to the sidewall of the outer wall surrounding the opening in the outer wall. The closed end abuts a surface of the inner wall.
