Heltec V4 Minimalist Case with Battery Switch and Optional GPS Support

This is a minimalist 3D printable enclosure designed specifically for the Heltec V4 (WiFi LoRa 32 V4) board.

The design focuses on clean lines, compact form factor, and practical usability while keeping the device lightweight and easy to assemble.

🔧 Assembly Requirements

• 4 × M3 screws (6 mm length)

• 4 × M3 nuts

• 1 × M6 Screw switch

The enclosure is designed for a secure fit using standard M3 hardware.

🔋 Battery Compatibility

The case includes space for an internal LiPo battery.
The battery used in this build measures:

10 × 34 × 50 mm

Batteries with similar dimensions should also fit, depending on tolerances and wire placement.

🔘 Physical Battery Switch

A dedicated opening is included for a physical inline battery switch, allowing you to completely disconnect power without unplugging the battery.

📡 Optional GPS Module Support

The enclosure is designed to accommodate an optional GPS module, making it suitable for projects such as Meshtastic or other location-aware LoRa applications.

🎒 Mounting / Carrying Option

The model includes integrated mounting holes, allowing you to attach a cord, carabiner, or strap.
This makes it easy to hang from a backpack, for example during hiking or mountain routes.

Perfect for portable LoRa projects, mesh networking experiments, hiking setups, and GPS-enabled builds.

🔄 Version Update – V2 Improvements

Based on feedback, the V2 Main Shell includes small integrated retention clips that firmly secure the Heltec V4 board inside the case.

The original version (V1) may not hold the board tightly enough in some prints. Fitment can vary significantly depending on your printer’s dimensional accuracy, material choice, and tuning tolerances.

The added clips in V2 improve stability and prevent unwanted movement, providing a more reliable and consistent fit across different printers.

If you experienced a loose fit with V1, the V2 design should resolve the issue.
