Machining Apple's Mac Pro Grille on a CNC

Since no one outside of Cupertino has yet to lay hands on the Mac Pro, I figured I’d try to recreate that instantly recognizable texture of the Mac Pro on the Shapeoko. Out of aluminum, of course… Er. ALUMINIUM, sorry.

And if we’re going to do that, we might as well also put it to the test, and see if the Mac Pro Grille design can really live up to its nickname, the Cheese Grater.

If you want to try 3D printing the model, I offer you this without any promises of help or support:…


  1. Note: People have commented before, and they'll likely keep commenting later but the reason I chamfered the edges is because Apple typically has a 5-10 thou roundover on all their hard edges. That's why you don't slit your wrists whenever you type on a Macbook. The Mac Pro likely has that sort of edge-rounding too, and I wanted this test to be more realistic. Accuracy is obviously important when so many people are counting on the results of this test to inform their purchasing decisions.

    Note: If you want to 3D print your own grater/soapdish to test, I posted the unchamfered version here:

  2. You know he’s telling the truth, when he be wearing an Apple watch on hand

  3. It doesn't matter if you are an apple fan or not you will enjoy this anyway.

  4. oh i thought it was 1 layer of big holes ontop of a layer of smaller holes, offset

  5. Dude i laughed Hard, thumbs up. The strand por this pc is 1k $ ??

  6. The only thing I want to complain about is that you had to use the part of the cheese next to the crust


  8. Tries to make something that will cut
    Proceeds to break sharp edges

  9. Just make sure you don’t actually you your Mac Pro as a cheese grater because you don’t want that going into the intake fans
