3D printing is amazing. If you are unfamiliar with the concept check out the following National Geographic video:

Now imagine having a tool from the 19th century, like this conformateur, a hat makers form:

It sits on little wooden feet, two of which are broken.  La Bricoleuse relates their experience repairing the tool using a 3D printer here. My understanding is they could have reproduced the whole piece, but why would they when theirs is such a lovely Steampunkish product, with a wonderful French name?
