I just took the stp file and mess with it for a bit, modified stp files are included for further messing if you're interested.
Two versions included, 40 deg and 60 deg.
Didn't really care too much about license but it sounds like a remix automatically inherit from its source, thus same GNU-GPL.
##Below is body of text copied from the source page.##Please use the tag "sourcetwo" when uploading files to thingiverse.com #The idea The SOURCE TWO is a collaborative open source frame project initiated by Team BlackSheep, targeted at FPV racers. It follows the footsteps of SOURCE ONE, a FPV freestyle frame.
The frame design is donated to the community to empower creators and makers, and integrate best practices and current trends faster into a continuously manufactured product. It's a cheaper alternative to clones that can be bought with the peace of mind that the big brands of the FPV industry stand for.

#Project license The frame files are released under GNU Public License (GPL) V3. More information here: https://www.gnu.org/licenses/gpl-3.0.en.html
#Project naming requirements SOURCE TWO is the name of the frame. If you are thinking about manufacturing it, you are expected to prefix the name with a brand name in order to allow customers to distinguish the different manufacturers, e.g. “TBS SOURCE TWO”. As a manufacturer you are also expected to denote the version number of the frame files that you have placed as basis of the project, e.g. “TBS SOURCE TWO V0.1”. If you have forked the project, you need to give it another name in order to avoid confusion between SOURCE TWO and your project. Accessories from the SOURCE TWO project also need to be named with the entire prefix, e.g. “TBS SOURCE TWO FPV Camera Adapter”. Unless the file is not compatible with certain versions of the frame, the compatible version number or version range also needs to be included in the name, e.g. “TBS SOURCE TWO FPV Camera Adapter V0.1 - V2”
