Possible to print in full PLA or full Metal PLA (I'm not stopping you)
but designed for PLA and Copper PLA.
Make sure you print in what material your nozzle can withstand ;)

Device AS PLA, Metal PLA 80% Copper
Case piece is made from PLA Black and Lid piece is made from Metal PLA with 80% powdered Copper in it.
For metal lid:
Get a medium-fine grit sanding paper and gently smooth out the edges before any color is applied to ensure a better paint lifetime :)
For both PLA and metal
To prolong the lifetime of any paint applied, or unpainted finish: spray a few layers of clear laquer onto the piece except the notches and studs
Step 1: The general shape of the inside matches the dimensions of the phone
Step 2: The cut-outs for the buttons and holes are shaped and smoothed
Step 3: The backside holes for the camera, flashlight and speaker are created and polished
Step 4: Lastly on the case, the 4 notches to secure the lid are placed 13 mm from the inner short wall to ensure stable mounting
Step 5: The general shape and thickness of the lid is created. 2 mm thick.
Step 6: The lid is extended 2 mm on the inside to ensure the phone wouldn't fall out easily and to not obstruct the edge of the display.
Step 7: The studs are shaped to height of 3.5 mm to ensure a buffer fit to the 4 mm deep holes in the case
Step 8: The lid is rotated to fit the notches in the case, and the overall edges are smoothed out
Finished and textured with a close estimation to the finished materials
Lastly, an assembly animation is created to show the easy press fit :)
