Student Project:Rocket TVC Gimbal With Tinkercad by canine rocket technologies

This is an older project but one of my favorites. It was a personal challenge and school project to teach myself CAD and test the limits of Tinkercad to put into application to the R & D process of rocketry. It was to design a TVC or Thrust Vector Control gimbal. TVC is the process of changing the vector of a rocket's thrust to allow it to control it's ight. This is more to show you my learning process and project journey with Tinkercad rather then details fo the system itself. If you want more details on the TVC system and want to build your own then check the links below. I will

also make a separate instructables detailing the system itself rather than the design process like this one Supplies:

Step 1: Introduction

So a few months back before I learned Fusion 360, I was using Tinkercad. I needed a complex rocket part a few months back and I didn't know F360, so as a homeschool project I decided to try and design it in Tinkercad. I saw https://bps.space/ and really wanted to build a gimbal design based on his system. No matter how much more complex things I've designed in Fusion360, this is still by far my favorite CAD and

3D printing project. I teach younger kids CAD sometimes in my free time and the #1 complaint is "You can't make anything cool in Tinkercad". Well just showing this project changes their minds and it makes me happy to be able to demonstrate the advanced capabilities Tinkercad possesses. Tinkercad is by far the best CAD teaching tool I have ever seen. It helped me to self teach myself CAD and teach others

too. It covers the fundamentals of 3D design, and I'm here to demonstrate what can be done with simple shapes and the fundamentals.

Step 2: The Design I had the basic design in mind, use 2 servos in a gimbal frame to vector a tube to hold a model rocket motor. So it was time to go and Tinker in CAD (terrible pun). It took almost 100 shapes in Tinkercad...See for yourself here by ungrouping XD

Step 3: Iteration After Iteration #2 discouragement I see when I teach other people CAD is when their design doesn't work on the rst try. I show them this picture and always tell them that everything nally worked at the 7th one. Iterative design is how it just gets better and better every time. One catch though, it requires patients and redesigning over and over ;) but keep it up! You're getting closer and closer to a working design every time your iterate.

Step 4: The Final Prototype Currently, I'm at V10 for this gimbal and am designing a new one in F360. But during this project V7 was the rst to work! I was happy with the nal design and a bit shocked that I had managed to actually use Tinkercad. It was time to stick a motor in and STATIC FIRE IT!!!!!!!!!!!!!!!!!!

Step 5: Test Fire...

It worked and it worked pehnominally! A few minor issue but in the end a great sucess! Since this is also a school project, I wrote up a report. You can read it here https://docs.google.com/document/d/1mH6wOfQzJGjTMxgqP0OAoqSD4kdoSnqfWhweJX8Z-OA/edit?usp=sharing

Step 6: Conclusion So what did I learn from this project? What can other students learn from this project? Well rst o it is absolutely possible to design something like this in Tinkercad. I wouldn't say this is the most optimal design, and surely I can now design this in with far better force distribution in F360 in about an hour or less, but it was a fun challenge. When I teach people CAD this is a great project I think others can learn from. I like to use this as a basic example of an idea to basic design to nal system. The end results can be very rewarding ;)

Anyway, I know this is a bit of a silly project, but I hope this was entertaining and educational in some way. I've long moved along with this project to more advanced things but I thought it would be something fun to share for others to learn from. Note: Anyone wanting details about the gimbals system, I have included links near the description. Also as noted I will write another Instructables on that soon. This was more to share my fun project

Step 7: Sharing Your Design I encourage other people to share their work. I did and not only did I learn a ton form feedback, but It also gave me cool opportunities! For example, someone ew my gimbal before I ever did and it worked! Sharing is one way to really enhance your's and other's learning experience. That's why I even bothered to make this to share the processes I went through to complete their project!

Excellent! I've made some model rocket nose cones using Tinkercad, but this puts my simple project to shame. Which I love! This is awesome to see, thank you for sharing. I really dig it. : ) Thank you! Yes I remember seeing your GoPro rocket before and I think you used Tinkercad on some part, proably the nose cone. Anyway glad you enjoyed it
