A rugged and compact case to house various sized pouch batteries and a heltec v3 lora board.
The board carrier and cover are slid into the case and the top lid clamps everything together to two m2.5 fasteners.
I designed this so that different boards could have carrier and covers made to slide in the main body.
There is not a great mounting option for the heltec v3 board, so i opted to unscrew the screen bracket and place the board carrier on the rear of the board, line up the screen bracket, board and carrier screw holes and replace the screws.
With the button pins fitted into the cover this is screwed into the brass inserts in the carrier, this tightens up to be a very secure and strong unit.
This can then be slid into the main case.
This design means you can print different coloured covers for the lora board to identify your nodes easily. Also, printing the button pin for the Reset button in transparent PLA allows the indicator lights to show through. There is also a screen-less option to hide your mistakes…
I printed everything in ABS except the transparent PLA pin and the PLA covers.
2.5mm Brass inserts should be used in the carrier and the case:
