This is the SR-71 Black Bird that many of you have been waiting for!
As I was designing this, looking at the materials, there were so many unexpected details.
And since they are so large, some patience is required to print them.
But I did my best to design it to be very easy to make while expressing all the details.

As I said before, I designed it to be as simple as possible, but with a few caveats.
1. The flap's hinges can be loose if printed incorrectly. If the hinge is loose, increase the flow rate, extrusion multiplier, etc. in the slicing program to print so that more material flows out and the gap between the hinge parts is narrowed. The hinge becomes stiff when the gap between the parts is narrowed.
2. Check the direction of the small red parts and attach them to the wings.
3. When attaching wheels to the rear landing gear, it is recommended to attach them with the wheel caps facing out.
4. I've made so many Snap fit connectors, but this plane is so long that it can wobble a bit. In this case, please use adhesive when connecting the body.

Check out the video for a more detailed process of printing and making.

I will be designing a display stand soon so stay tuned!
