Eyeball Sub-Assemblies

These are the four bench-built parts that fit inside the eyeball housings. Build the Camera Assembly and either LED Assembly first, then wrap each in an Eyeball Assembly.

Camera Assembly

Tools:

  • Cross-head screwdriver
  • 2.5 mm Allen key
  • Sandpaper (optional)
Part Qty Notes
IMX296-MPI_Eyeball_6mm_camfered.stl 1 Remove support material
ISO 4762 M3x6 mm screw 2 6-15 mm; cylindrical head
M2x10 mm self-tapping screw 4 6-12 mm
Camera 1
  1. Remove all support material.
  2. Smooth spherical surfaces if needed.
  3. Chamfer or prime the two horizontal holes for M3x6 mm using a cross-head screwdriver.
  4. Install both M3x6 mm screws with the Allen key. Ensure straight alignment.
  5. Slightly loosen the aperture and focus screws on the camera. Align them with the slot. The ribbon cable connector must align with the opening.
  6. Attach the camera to the eyeball using four M2x10 mm self-tapping screws.

Note

Choose the appropriate eyeball for your camera and lens. See Variants on the 3D Printing page for the alternate eyeball STLs (2.8 mm or 6 mm, camfered or plain).

LED Assembly (5x2 IR LED board)

Tools:

  • Cross-head screwdriver
Part Qty Notes
5x2IRLED_Eyeball.stl 1
5x2 IR LED board 1
M3x10 mm self-tapping screw 2 8-12 mm
  1. Remove all support material.
  2. Smooth spherical surfaces if needed.
  3. Insert the already wired 5x2 IR LED board in the 5x2IRLED_Eyeball. Match electric polarity.
  4. Install the four M3x10 mm self-tapping screws. Do not overtighten.
  5. Clip the cables in place and ensure correct polarity. Keep the cables as far apart as possible.

LED Assembly (Legacy COB)

Tools:

  • Cross-head screwdriver
Part Qty Notes
LED_Eyeball.stl 1
LED_Clamp.stl 1
100 W COB IR LED with wires 1
60 deg LED Lens (44 mm + Reflector) 1
M3x10 mm self-tapping screw 4 8-12 mm
  1. Remove all support material.
  2. Smooth spherical surfaces if needed.
  3. Insert the reflector in the LED_Eyeball.
  4. Insert the COB LED in the reflector.
  5. Position the LED_Clamp on the COB LED. Ensure that the centering pins of the LED_Clamp are engaged with the COB LED holes. Ensure that the LED cables are not squished.
  6. Install the four M3x10 mm self-tapping screws. Do not overtighten. The clamp is designed with clearance, so that the LED is always preloaded.

Tools:

  • 3 mm Allen key for ISO 7380-2 or 4 mm for ISO 4762
  • Sandpaper (optional)
  • Superglue (optional)
Part Qty Notes
Camera Assembly or LED Assembly 1
EyeScreen.stl 1
EyeScreen_Clamp.stl 1
ISO 4032 M5 nut 4
ISO 7380-2 M5x20 mm screw 4 20-25 mm; ISO 4762 optional
  1. Remove support material.
  2. Smooth spherical surfaces if needed.
  3. Insert M5 nuts into the EyeScreen_Clamp pockets (optional: secure with superglue).
  4. Insert the Camera Assembly or LED Assembly into the EyeScreen.
  5. Ensure correct orientation: notches must face upwards (toward the ribbon cable).
  6. Install the M5 screws and tighten only lightly.

Note

ISO 7380-2 button-head screws look nicer and provide more surface contact. ISO 4762 offers better tool access.
