🛠 Assembly Instructions

Fitment: Parts are designed tight to help reduce water ingress

1. Clean Up the Holes

Use drill bits to clean out any print artifacts:

• 3 mm holes: 7/32" drill bit

• M2 holes: 3/16" drill bit

• Lens opening: 11/64" drill bit (Most likely required for correct fitment) 

• Antenna tube hole: 7/32" (or match your specific antenna tube size)

2. Prepare the Weather Stripping

• Apply adhesive foam to the top side of the enclosure.

• Use a soldering iron to melt a hole into the foam for the LED lens—be careful not to melt the plastic underneath.

3. Install the LED Lens

• Apply super glue around the inside perimeter of the lens opening.

• Press the transparent lens into the top‑cover opening until fully seated and flush with the top.

4. Install the Nuts

• Use an M2 screw from the top to draw each nut into its slot on the bottom half of the enclosure.

5. Seal the Cable Entry Points

• Place small strips of weather‑strip foam inside both the top and bottom cable‑entry channels.

• When the enclosure is closed, the foam will compress around the cable, improving the seal.

• Optional: Add a small bead of silicone sealant inside the main enclosure channel for increased water resistance.

  • Do NOT apply silicone inside the wire‑entry holes—the foam alone should be sufficient for sealing those.

6. Mounting to the X‑Maxx

• Slide the enclosure over the two screw pins on the front X‑Maxx rails.

• Make sure the cable of the OTA exits toward the rear of the X‑Maxx.

• Secure the enclosure using the two M3 × 15 mm screws.
