Of Microplastics and Metal : What case for my cyberdeck?

Almost done with my cyberdeck, but have one more issue to solve: I am terrible at turning an assortment of physical parts into digital information.

Do i :

Suffer through 3D modelling the same thing 20 times, wasting KGs of filament?

Or:

Make the thing out of metal and foam ONE TIME, but deal with it being heavier than it should be?
