I would first ask if this is some kind of safety panel because you might just be putting yourself or your boss in a heap of liability.

After that, I would say you need someone to design the panel. And if you need 5 for the life of the project, order them printed from a 3D printing company. Can't design a panel? People know how to do that too.

And of course you have to ask, is 3D printing this panel the -right- solution when a set of tin-snips and some HVAC sheetmetal would do a better job.
