I picked up a Pelican Case (iM2500) that I've seen at many surplus stores:


These cases were used to transport Mechanical Ventilators during the pandemic. Good news for us is you can get a really good price on a Pelican iM2500.
However is has been modified. A Harting Hans B connector has been added to the side.

I have a few project in mind for this case and one of them require getting power in to the case. I figured since there was already a hole, why not use it?
I designed up a plate that will hold one or two pairs of Anderson Powerpole connectors (15-45a)
Printed with PETG .2mm layer.
I printed the Tight Fit versions and they worked perfectly. I included a version with an extra .2mm in case it's too tight on your printer.
I used an M2.5x16 screw to hold the APP in place. I used four M3x8 screws to attach the plat to the Harting Connector.
