We are glad to see the progress of [foaly] 3D printing cortex 2 rocket. The latest construction log is full of beautiful pictures and design details. This rocket war is not only full of efficient electronic technology and intelligent design, but also seems to prove that 3D printing is far from what some people think is novel.

In such a rocket, cable management and component layout are by no means a trivial matter.
There are too many things going on in cerebral cortex 2. If you don’t have the ability to manufacture your own parts completely according to the specifications, you can’t do anything. In fact, there are too many things going on, and cable TV management itself is a challenge.
Everything in the build log is interesting, but the design of the parachute system is particularly noteworthy. [foaly] the original cortex rocket ended when the parachute could not be deployed, and cortex 2 was determined to avoid this fate as much as possible. For parachutes and any ropes and anchors, careful layout maximizes the chance of successful deployment without any confusion, but there are some additional functions. The panel covering the parachute is installed with the help of four magnets with opposite polarity. When the door is servo unlocked, this provides an initial repulsion, which will help the wind immediately rush into the opening and blow the panel away. The recycling system even has its own special microcontroller, which can operate independently; Even if other software crashes, the parachute will still deploy. Locking the connectors of all cables also ensures that the acceleration force does not move any contacts.
Everything about the rocket looks great, especially the workload of software. The console even has an interactive pre flight checklist, which is a great function.
The last time we saw cortex 2, it was only half. We couldn’t wait to see its performance. Rocket technology is a field that benefits greatly from 3D printing, the availability of highly integrated electronic products, and even the rocket design workbench of freecad. After all, better tools can do better work.
