1 Print Drilling Templates¶

We will use printouts of the PDF templates to mark the positions of the holes to drill. Download the insect-detect-docs repo and go to PDF_templates/drilling_templates/version_2024. Print all PDF templates in original size and cut them out. We will attach them to the enclosures, mounting plates, HPL sheets and aluminium square tube in the next step.

Actual size

Make sure to select Actual size for printing the templates in their original size.

2 Mark Hole Positions¶

Use a small strip of adhesive tape on each side to fix the drilling templates to the enclosures, mounting plates, HPL sheets and aluminium square tube as precise as possible.

Position a nail or screw in the center point of each green circle and hit it lightly with a hammer to mark the drill holes (recommended for mounting plates, HPL sheets and aluminium square tube).

Use a different pointed tool and push it carefully but with sufficient pressure through the template (recommended for enclosures).

Remove the template printouts after marking all holes and keep them as reference for the respective diameters while drilling.

3 Drill Holes¶

3.1 Enclosures¶

You will need a 6 mm metal drill bit (hole for ventilation plug), a step drill bit with 20 mm step (holes for M20 cable glands), and a 19 mm forstner bit or similar (hole for optional LED button). It is recommended to secure the enclosures in a bench vise while drilling. Drill a small hole (~3 mm) at the marked position for the LED button before using the forstner bit to keep it in position.

3.2 Mounting Plates¶

You will need a 3 mm and a 4 mm wood drill bit for the mounting plates. If available, use a drill press to drill the holes more accurately.

3.3 HPL Sheets¶

Continue with 5 Apply Screen Protector if you are using your own custom mounting solution!

You will need a 4 mm metal drill bit for the HPL sheets. Drill rather slow, as the bit and sheet could overheat otherwise (stop if you see smoke).

3.4 Square Tube¶

You will need a 4 mm metal drill bit for the aluminium square tube. Drill slowly, to avoid overheating. Drill the 4 mm holes through both sides of the tube.

4 Attach HPL Sheets¶

Attach the HPL sheets to both enclosures now, as it would be more difficult later on when the hardware is already integrated.

4.1 Electronics Enclosure¶

We will start with attaching the 12x24 cm HPL sheet to the larger electronics enclosure.

Allen Key (3 mm), Pliers

8x Hex Nut M4, 4x Washer, 4x Screw M4 (16 mm)

HPL Sheet (12x24 cm) with drilled holes

Bocube Enclosure B 221309 PC-V0 with drilled holes (lid removed)

Drop one of the M4 16 mm screws into each hole in the corners of the enclosure. Shake the enclosure for the screw to completely slide through the hole or use the allen key to guide it.

While holding the screws in place with the allen key, fix them to the enclosure with one M4 nut each. Don't fasten the nuts too tight yet, we will do this in the next step.

The enclosure should now look like in the following image, with all four screws securely attached, but not yet fastened tightly.

Push the HPL sheet onto the four screws and press it down, to make it sit flush on top of the nuts. If this is difficult, loosen one or several of the nuts, to be able to adjust the screws to the holes in the HPL sheet.

When everything is in place, use the allen key to fasten the screws + nuts, while pressing against the HPL sheet from the other side.

Put the four washers onto the screws and then use pliers to fasten the remaining four nuts tightly. The HPL sheet is now securely fixed to the electronics enclosure for mounting later on, while enabling airflow between enclosure and HPL sheet for better heat dissipation.

4.2 Camera Enclosure¶

In this step, we will attach the 10x20 cm HPL sheet to the smaller camera enclosure.

HPL Sheet (10x20 cm) with drilled holes

Euromas Enclosure M 215 G with drilled holes (lid removed)

8x Hex Nut M4, 4x Washer, 4x Screw M4 (2x 16 mm + 2x 30 mm)

Allen Key (3 mm), Pliers

Drop the two M4 30 mm screws into the corner holes on the side of the enclosure where you drilled the 20 mm hole (these will be used to attach the platform frame later on). Drop the two M4 16 mm screws into the corner holes on the opposite side of the enclosure. Shake the enclosure for the screws to completely slide through the holes or use the allen key to guide them.

While holding the screws in place with the allen key, fix them to the enclosure with one M4 nut each. Don't fasten the nuts too tight yet, we will do this in the next step.

The enclosure should now look like in the following image, with all four screws securely attached, but not yet fastened tightly.

Make sure that the side of the HPL sheet with the 4 mm hole in the middle is located at the side of the enclosure with the 20 mm hole and longer screws. Push the HPL sheet onto the four screws and press it down, to make it sit flush on top of the nuts. If this is difficult, loosen one or several of the nuts, to be able to adjust the screws to the holes in the HPL sheet.

When everything is in place, use the allen key to fasten the screws + nuts, while pressing against the HPL sheet from the other side.

Put the four washers onto the screws and then use pliers to fasten the remaining four nuts tightly. The HPL sheet is now securely fixed to the camera enclosure for mounting later on, while enabling airflow between enclosure and HPL sheet for better heat dissipation.

5 Apply Screen Protector¶

To make the clear lid of the camera enclosure scratch resistant, we will apply a screen protector. The protector doesn't have to fit perfectly, but should cover the OAK camera lens completely.

Clean the clear lid thoroughly with a microfiber cloth. Follow the instructions that came with your screen protector to avoid bubbles forming between lid and film.
