DIY Box with Adjustable Power Supply & T12 Iron

How to assemble a box that integrates an adjustable power supply, a T12 soldering iron, and a charging port, and ensure that all functions work properly?

The main power input line from the mains is located at the bottom of the Mingwei casing, and the branches are connected to the independent switches of the three modules. The output end of the adjustable power supply is equipped with a 65-degree normally closed temperature control switch, which is pressed on one of the SC3320s to prevent the temperature from abnormally rising and damaging the power supply after the fan malfunctions. Anti-backflow protection has been added (two 10a10 diodes connected in parallel to the positive pole). The voltage detection wire of the meter head is behind the two diodes connected in parallel to prevent the voltage drop of the diodes from affecting the display of the meter head. An anti-reverse module has been added (positive and negative pole anti-parallel 10a10 diodes + fuse scheme); Another 3320 has a 50-degree normally open temperature control switch for the fan.
