Hi guys, want to share with you mu recent project.
This is external binding posts addon to HP 6623A 3 output power supply.
3d printed contraption can be attached on either side of the PSU. 3xM4 screw attach box very securely to the side of the PSU.
Box has 6 holes matching Pomona binding posts cutouts. 3mm walls make box quite sturdy.
Wire go all the way to the back. Sense wire not really necessary because top current is 4A, drop wont be that big. But I will add them eventually.

Here are all photos:

Future improvements: add 3 switches to enable-disable each output via Relay Option my PSU has.
