I needed to create a housing for a mains AC input and DC output to control the electronics on my printer enclosure. This is designed around a specific AC power socket for a NEMA 5-15P to IEC 60320 C13 cord.
Outside of the power socket which has a specific opening size, you could use any kind of output cord. The provision for the voltage/ammeter was mostly for fun, but helpful for seeing how much power is being consumed.
The author marked this model as their own original creation.
