Tomorrow is a big holiday in the United States and this app is the perfect way for anyone with a MakerBot to make it special. And delicious.

The company dreamforge has put up a genius custom cookie cutter app for all to enjoy. Introducing Cookie Caster.

It’s web-based, and sits right inside the homepage. You can draw your cookie cutter freehand, or trace an image that you upload from your computer. As you work, the app lays down two end points to each line that you draw, with one point in the middle that you can drag to create curve. That means you really don’t need too many points in your shape if you’re tracing. Just get the basics down and add curvature later.

Once you’re finished, you can save the file to the Cookie Caster gallery (you can see my test triangle, labeled “Pelkertron” because I don’t understand naming things, or my truly terrible Dollar Sign shape). But even better,  you can download the .stl for free and make it right away. If you have a MakerBot, this means you can make custom cookie cutters in minutes. If you don’t have a MakerBot, you can pay a fee to have the Cookie Caster folks send you your finished product. Sweet!

Let’s be sure to give credit to the awesome cookie cutter work of Guru, which inspired Cookie Caster. They say in an email that their app has just made some simple updates to Guru’s and put it on the web.

One possible enhancement to Cookie Caster that stands out would be the ability to add interior shapes to my cookie cutter, like the hole in the middle of a doughnut. Try out the app and throw your feedback in the comments below.

If you come up with any good 4th of July designs, or designs for your own country’s holiday, share them in the Cookie Caster gallery and on Thingiverse!
