Berkeley-based drone manufacturer 3DRobotics has teamed up with 3D printable model marketplace MyMiniFactory to release a free 3D printable version of their flagship drone the IRIS+. All of the 3D printable files for the IRIS+ are available exclusively to the MyMiniFactory community, and can be downloaded for free. MyMiniFactory users simply need to purchase the electronic components directly from 3DR and they can build their own IRIS+ drone.
