This 35 mm diameter emblem is perfect for attaching to your Ultimaker selector button or anywhere on the outside framework. I use these in my classroom to name my 3D printers. The high school engineering design students I teach love them and often design their own. I used Inventor to create it, and have uploaded those .ipt files as well. With a slight modification they make great key chains. Enjoy! *See images of all my [Superhero Emblems HERE](https://goo.gl/photos/cSmpRzrHtiUp29zy9)*
