Trumpet 3D Printed While Being Shipped: Rush Job

This fun commercial for Dutch parcel company PostNL took advantage of 3D printing to deliver a trumpet that did not exist until after the box that it came in was shipped.
With the help of 3D printing expert Joris van Tubergen, PostNL supposedly sent an Ultimaker 2 3D printer (and presumably a power source) through the usual stages of delivery while the machine printed the trumpet.
