This sign features a round U.S. Submarine Force “Silent Service” sign mounted as a double-sided projecting wall display. The face of the sign has a soft glowing green background with a black outer ring and bold black lettering.

Around the top edge it reads “U.S. SUBMARINE FORCE”, and along the bottom it reads “SILENT SERVICE.” In the center is the Submarine Warfare insignia (dolphins)—a submarine flanked by two stylized dolphins—rendered in black, giving the sign a strong naval and military identity.

3D Printed Support Description

• The sign is mounted using two black 3D-printed wall brackets installed vertically on the wall.
• Each bracket includes a rectangular mounting plate that is secured to the wall with screws.
• Extending outward from each plate is a straight horizontal support arm that projects perpendicular to the wall.
• The upper arm connects to the top center of the round sign through a short vertical hanger post.
• The lower arm extends beneath the sign and connects to the bottom center using a second vertical support post.
• These two vertical posts hold the sign securely between the arms, stabilizing it and preventing rotation.

Structure and Appearance

• The brackets appear to be 3D printed in black filament (likely PLA or PETG) with a smooth matte finish.
• The arms use a simple rectangular beam design, providing strength while keeping the mount visually minimal.
• The bracket system forms a rigid projecting frame, allowing the sign to extend outward from the wall so it can be seen clearly from both directions.

Overall, the setup creates a clean military-themed hanging display sign supported by sturdy 3D-printed black mounting brackets, emphasizing the glowing U.S. Submarine Force “Silent Service” emblem.
