Luxonis OAK-D-LR 6 mm Faceplate Extension Adapter Arducam Camera

A 6 mm extension adapter that moves the OEM front faceplate of a Luxonis

OAK-D-LR forward by exactly 6.000 mm, without giving up any of the way the

camera originally held that plate on.

I added an Arducam lens and wanted to retain the faceplate, so I made this.

WHY

The OAK-D-LR faceplate is retained by three things: a two step lap rim, two

side snap clips, and a single captive M4 thumbscrew underneath. On top of

that, four bosses on the back of the plate plug into the rubber mid case

seal and grip by friction.

Simply spacing the plate out breaks all of it. The bosses come out of the

rubber, the clips no longer reach their catches, and the M4 nose no longer

lines up with its hole.

This adapter puts every one of those back.

WHAT IT REPRODUCES

Rim: the cover's two step lap rim is copied from the original, so the

adapter seats on the camera exactly as the plate did.

Side clips: the plate's own tabs are copied at their original height, and

the mid case catches are copied 6 mm up, so the plate still snaps on.

M4 lock: a bracket carries the securing tongue back down to its original

position, so the factory M4 thumbscrew still pins it.

Bosses: four posts run back down into the rubber seal, slightly larger than

the OEM bosses for a firmer grip, with a 45 degree fillet at the root.

Sleeves: four collet sleeves receive the plate's own bosses, with pilot

holes for M2 set screws if you want a positive lock.

SIZE

201.6 x 43.6 x 20.0 mm, about 9.3 cm3

HARDWARE

Reuse the camera's original M4 captive thumbscrew.

Optional: 4 x M2 x 6 mm thread forming screws for the sleeve set screws.

PRINTING

Material: PETG or ASA for outdoor use. The collets need to flex and this

part usually lives outside. PLA will probably be fine indoors.

Orientation: tall parts up, as modelled.

Supports: normal or grid, interface on, 2 to 3 interface layers, 0.15 to

0.20 mm interface gap, 0.7 to 0.8 mm XY separation.

Perimeters: 4

Layer height: 0.2 mm

The thin skirt ring on the underside is the surface that seats against the

camera, so use a support interface and check it comes off clean.

ASSEMBLY

1. Slide the OEM faceplate onto the adapter. The four bosses enter the

sleeves and the two side clips engage.

2. Optional: drive the four M2 set screws through the sleeve pads.

3. Lower the assembly onto the camera. The four posts enter the rubber seal

and the rim seats.

4. Run the M4 thumbscrew in from the bottom.

PLEASE READ, FIELD OF VIEW

The three lens apertures are unchanged in size but now sit 6 mm further

from the sensors, so they subtend a smaller angle and you will get more

vignetting at the edges of frame. Nothing in the adapter can fix that. It

would need the apertures in the cover itself enlarged. If you are running

wide FOV modules, test before you commit to this.
