LOCASYNC Smart Tag Outdoor Wall Enclosure — IP-rated, Dual Sealing

## Overview

A weatherproof, wall-mountable enclosure designed for the LOCASYNC Smart Tag (Google Find Hub / Find My Device compatible Bluetooth tracker). Originally designed for tracking items in unattended outdoor locations — garages, sheds, gates, vehicles, garden equipment. The case uses dual sealing: a primary O-ring around the device pocket and a secondary tongue-and-groove labyrinth around the full perimeter — significantly better dust and water resistance than a simple snap-fit case.

## Key Features - Dual sealing — O-ring + tongue-and-groove labyrinth around full perimeter - Wall mountable — 2× M4 countersunk screws, mounting heads hidden inside the case - Robust closure — 4× M3 screws into brass heat-set inserts (Ruthex M3 compatible) - Built-in alignment — 2× large rectangular snap features keep parts aligned during closure - Elliptical locator peg — engages the device's button cutout from the inside, prevents rotation - Pry slot — for emergency opening if O-ring sticks - No supports needed — both parts print flat with parting line up

## Assembly

1. Print both parts (back tray + cover). 2. Install heat-set inserts in the back tray: - Preheat soldering iron tip to 200–220 °C (PLA) or 240–260 °C (PETG) - Place insert on tip, press perpendicularly into the M3 hole, hold 5–10 s - Verify the insert is flush with the surface and doesn't spin after cooling 3. Mount the back tray to the wall with 2× M4 countersunk screws. 4. Install the O-ring in the inner groove. Cut the cord to length, glue the ends with cyanoacrylate (superglue) for a continuous seal. 5. Insert the Smart Tag into the pocket. The locator peg engages the device's button opening. 6. Lower the cover — snap features engage the slots, tongue enters the outer groove. 7. Tighten the 4× M3 closure screws in a cross pattern (TL → BR → TR → BL) to 1–2 N·m. To open: unscrew the 4× M3, then insert a flathead screwdriver into the pry slot at the bottom edge of the cover. ## Notes - The case is designed around the LOCASYNC tag's measured dimensions (30 × 53 × 9 mm). Other similar Bluetooth trackers may not fit. - The locator peg engages the LOCASYNC's circular speaker/button opening on the back. Tested with this specific device. - For best weatherproofing, mount with the pry slot facing DOWN so any condensation drains out. - The case is not pressure-rated — it's designed for splash and driven-rain resistance, not submersion.
