Tamper for our Krups espresso maker (which didn't include one). It prints out at 49 mm in diameter giving just enough clearance so it doesn't get stuck. Modeled in Blender 2.71. Corrected: it said Braun earlier. Hope this didn't cause anyone problems. And I added an actual photograph of the printed model.This was modeled in Blender 2.71 on my Macbook Pro. I don't have a picture of the printed project yet because it finished late last night. However, it fits perfectly in our espresso maker.
