Case made from FormFutura's Copperfill.

This is a PLA type of 3D printer filament with 80% copper filling. It 3D prints heavyweight copper parts which are nearly indistinguishable from genuine copper cast objects.

Post-processing was done with vinegar and salt (plus clear coat for durability).

The keyboard is Hummingbird by PJE66, built with Choc Robins and 15g springs.
