Heltec v4 case - "The Brick"

The Heltec v4 is thirsty for electromotive force. I wanted something rugged, with plenty of capacity.

There's plenty of room inside for a LiPo pouch cell or a few 18650s.

Need to complete the unit:

• Heltec v4 (with or without a GPS unit)

• SMA pigtail

• An antenna with a matching SMA connector

• Slide switch with 18mm screw spacing

• (Qty 14) M2 x 6mm hex socket head cap screws

• (Qty 12) M2 brass knurls and something to melt them into the frame
