MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
I understand your opinion, We are doing this because other users are already doing this since time ago and was accepted by thingiverse. You can see an example here https://www.thingiverse.com/stephencz/designs.
We are sharing the complete fuselage, it is explained in the tittle and in the description.
Many people print the fuselage just for fun, others use it like test part to make sure that they are satisfied with the results before buying the model.
In addition to this we are giving for free many RC accessories like landing gears, horn cover, spinner... so that many people can use this things for conventional RC airplanes. We are planning to design and share for free more accessories,
