Vỏ Heltec V4 - Pin 18650 / N-Type Connector

Due to its small size, it is NOT suitable for pass-through N-type connectors, but ONLY for those with a 4-hole base. See the photos for details.

I made the @SDM case smaller and more compact, minimizing the internal space and thinning the walls where possible.

Required materials:

- 3 self-tapping screws for the cover

- 4 self-tapping screws for the N-type connector

- 1 18650 battery holder.

- 1 UFL IPEX to N-type female connector with 4-hole base.

- 1 Heltec V4 board.

- Heat-shrink tubing or electrical tape to connect the 18650 battery holder cable to the Heltec board.

- Soldering iron + solder + solder paste.

I printed it in ABS, no support required.
