Bench power supply

I designed this simple bench PSU to have one variable DC output and 2 x USB A ports. It’s based on a 19v 65w Dell laptop power supply that I had lying around but I wouldn’t recommend this route to others. 

If I were to design it again, I’d add more supports to hold the bottom panel in place.

You can find the .stls here.
