Two piece case with integral cooling fins. Used my Raspberry Pi reference model to make this.

The two pieces are intended to be 3d printed at 101% of the as designed size, then investment cast in aluminum. The "top" piece with the fins is designed with 75% thread engagement holes for M2.5 screws. Tap these four holes. The four holes on the bottom piece should be a close fit for an M2.5 screw.

If you want to cast it in a different metal, use the appropriate multiplier.
