The Hermes head bezel cover is the front frame of the robot’s head that surrounds and protects the 2.8-inch display.
Its main jobs are to:
- Hold the display in landscape orientation
- Expose only the active screen area through a rectangular window
- Hide the display PCB, wiring, and unused border
- Protect the glass from direct impacts
- Attach to the rest of the head enclosure
- Provide the robot’s finished “face”
The display is installed from behind. Its rear PCB face rests against internal supports, while clips or screws retain the PCB around safe edge areas. Nothing should press directly against the LCD glass, solder joints, connectors, or rear components.
Planned clearances are:
- 0.5 mm around the display window
- 0.5 mm around the display PCB
- 1 mm beyond the tallest rear component
- Cable space behind the display for a gentle bend and service loop
The bezel should be printed face-down if that produces a clean window edge without internal support material. The final window and support geometry must still be adjusted to the measured Adafruit PID 1770 PCB outline, active-area position, rear depth, and mounting pattern before the final print.
