MakerBot has released its official app for Android on Google Play. MakerBot Mobile adds convenience to the 3D printing process. You'll be able to access designs from your MakerBot Cloud library, or download designs from the MakerBot Thingiverse and print them wirelessly from the app.
You can manipulate and prepare designs before printing them. MakerBot Mobile allows you to optimize and scale your design, and slice it for 3D printing on a layer-by-layer basis, all powered by MakerBot's servers. If something isn't in your library, you can print it from the MakerBot Thingiverse app, which will send designs to the MakerBot Mobile app for printing.
When you're ready, all you need to do is confirm the print on your MakerBot Replicator 3D printer. You can use the app to control your printer, and watch through the Replicator's camera as your build progresses.
MakerBot Mobile is available on the Google Play Store right now, so download it and get printing.
