Case for TypeC PD 20V+Step Down Module*2

I design a case for output 20V & 2 of variable lower voltage,
one of step down module can easily adjust from outside.

I use this module to output 20V+12V+5V to test a lot of electric devices and it works great.

Needs:
PDC004-PD X1
MP1584EN DC-DC step down X2
A little hands-on welding skills
