This is a dps5005 based power supply with integrated 36v 3A Delta power brick and a 30mm fan.
It probably does not fit for you but i include a fusion360 project file.
Usb connection is also supported and the cooling is good enough for longer use.
Here is a video of it in action: https://youtu.be/LBkTJ6NCcdg

Print with the flat side facing down and you probably need no supports.
