This is my first ever upload, apologies for the huge amount of geometry. I highly recommend you download and open the blender file first, or make sure all your work is saved before opening the .obj or .stl files, as it may crash your program.
This is a spaceship I designed, loosely based on the manta ray sea creature. It is a space fighter, designed for chasing and dogfighting.
It has landing gear and giant cannons on the tip of each wing, which can rotate 270-360 degrees. I know the description says it is not rigged, but in the blender file, it is 'loosely' rigged, which means you can rotate the wings and move the separate emergency cockpit/mini escape pod using the bones system I have set up.
As an added bonus, in the blenderfile 2nd layer, I have also modelled the landing model, with the landing gear exposed and landing on a flat surface. The legs are also rigged, but not very efficiently, as I'm still getting used to the blender rigging system. If you have any specific requests of spaceships, let me know and I'll gladly model them for you!
