The entire project is based on the inexpensive Pawbol S-box 216 enclosure. The kit includes an insert for mounting the battery and the internal circuitry inside the housing. Different hole-grid sizes are available; 3×3 is recommended.

The device is mainly mounted behind the antenna on the mast. The enclosure bracket is only used as support and can be secured with cable ties. Alternatively, for lightweight antennas with an SMA connector, you can use only the enclosure’s rear bracket.

For outdoor use, it was printed in ASA.

I used A2 screw 4x16mm and 5x25mm  screws visible in the photo.

The project also includes spacer washers designed for use with 1/4" metal screws  S07 and S29 available on AliExpress. Two types of washers are provided depending on the diameter. Additionally, a vertical holder for snapping into the grid is included for mounting the TP4056 charger board.

A small gap is left under the solar panel where you can stick small strips of double-sided tape, which significantly improves the mounting of the solar panel.

For the black solar panel, the mounting bracket is slightly different. During printing, pay attention to which panel you have and which bracket should be printed.
