Description
I made this to fit a 3000mAh battery and an external antenna. It houses the battery on the bottom layer of the box, then the insert holds the Heltec V4 board. The GPS and WiFi antenna lay down on the inside, and there is a port for an external antenna if you choose to use one.
This recharges via the built-in USB-C port.

To assemble, place the battery in the bottom of the enclosure. Then you plug in the antennas to the Heltec board. Insert the external antenna through the hole and fasten it with the included washers and nuts. Plug in the battery to the Heltec board. Insert the Heltec board's DIPs into the platform, and guide the platform and board into the box. Fasten it down using 2 M3 screws. Arrange the antennas to sleep comfortably in the top section of the enclosure, and fasten the lid to the top.
I printed mine using PETG in multiple colors. If you don't have a multicolor printer, monochrome it shall be.
