The field box uses the Omnifixo Base as a lid and of course uses magnets as fixation. It can fit a TS80 soldering iron, a knife, some solder. It also has a built in soldering iron stand…what else do you need?
The "soldering stand" is build from M3 clevis/Quick link and pushrod for RC Planes plus a round crimp connector.
