I did some revisions to the 3d printed keychain, which I previously used to make the video with the hammer.

Received the new 3d print in the mail last week, and put it on the ring with my keys. At the time of writing this, it's still intact, with only some minor scratches that you'd normally have on any plastic keychain.

You can order one over at Shapeways for yourself, with picture and inscription of choice, doesn't cost much and shipping is included.
