I was showing off some of my designs at a recent Makerbot user group meeting, and I wished I had tags for them with QR codes and some other relevant data. This bookmarklet will generate such tags.

Note: I initially set the license to CC-BY for the example picture because the CC licenses look a little nicer on the tags, but I've changed the license to PD, so feel free to use it however you want.

Update: Some errors were reported with the DOM walking, so I rewrote those portions to use Regex instead. This should improve compatibility.

Thingitag is now integrated into thingiverse. You can get it by clicking the "print tag" button below the license statement on any Thing page. No more dealing with cross-browser scripting headaches and rewriting every time the thingiverse design is tweaked!

Old instructions:

Navigate to the page for the Thing you want to tag, then run the script. It will grab the relevant data and format it for tag printing. I haven't done extensive testing, but it should work in all standards-compliant browsers (old versions of IE might have a problem).

Print the tag, cut it out and fold it over. Fold the end over into a triangle (for strength), then punch a hole and attach with string to the printed thing.

Note: Thingiverse won't let me post a javascript link (this would be a security issue), and the text gets a little mangled if I post it here. To get the script, download the .js file, copy the contents and paste it into your address bar or create a bookmark using the full script as the URL.

Update: for those still having trouble, you can get bookmarkable links for Thingitag and Thingitag Jr. at http://whosawhatsis.com/paraphernalia/thingitag.html

Update: I fixed these for the new Thingiverse design AGAIN, and I'm getting sick of it. It works, but I've only tested it in Chrome. If your browser of choice doesn't work, use Chrome instead.
