I made a new 3D Printer Designs Windows Store app over the weekend using Microsoft Siena (beta). The 3D printing app displays the 30 most recent MakerShop designs in a gallery view. You can click on one of the gallery items to see the details about the 3D printer design and click a button to download it from the website and 3D print it at home or using a service like i.materialize that will mail it to you.
Siena is basically a Windows Store app (Metro app) that makes Windows Store apps. It can pull in data sources like RESTful services and you can quickly data bind them to common UI controls like galleries. You can add buttons that navigate to detail screens or to websites. Siena is still in beta and when it gets to publishing your app, you still have to bring it in to Visual Studio to complete the process, but I foresee that not being the case when it is released. I have heard that the app will be named AppMagic once it is released out of beta.
