3d print emi honeycomb?

[coppercone2]

had a interesting idea, to make those honeycomb EMI filter vent panels by 3d printing and paint dipping the parts. I found this

I have a chassis I will be working on that can be used for tests before its filled (it has connectors and plenty of vent holes)

thought someone might find the idea useful
