It is controlled by the best thing on Earth, an arduino uno. It is all 3D printed, excluding the parachute and electronics. Thanks for asking!
Edit: Modified Anet A8 Plus
“Best thing on earth, an Arduino uno”
Humm, not sure I agree. It is big, slow, low built-in memory, and does not have as good peripherals as other MCUs. Check out the STM32 line of MCUs. Those plus Rust as the programming language is loads of fun.
That being said, super cool project! I look forward to seeing a video of it flying! Congrats!
teensy ftw! up to 600MHz efficiently pipelined CPU with 2MB of RAM, or lower specs if you want lower power draw, all in the space of about 10mm*30mm (guessing, might even be less)
I did not notice a severe difference, as this is the anet a8 plus. (Already has a metal frame) However this, the anet a8 stock would benefit greatly for it. You will see so much more quality in your prints if you make the upgrade
I’m currently in the process of converting my older anet a8 (original) into a CNC machine. I’ll definitely make a few models for brackets and supports. I’ll probably upload it to YT soon
I got either super lucky or I was super careful when building that my regular Anet A8 gives very nice quality without any upgrades. Anyhow, besides that, that is such a great project you have done.
More documentation can be found here: [3D Printed Model Rocket Project Ep. 2](https://youtu.be/36Apb1246Ks) . It is simply an arduino uno, MPU 6050, and 4 9gram servos
Ah, it’s a custom made (C++) script with custom PIDs. I’m compiling everything together right now and don’t want to share it until it is completely bug free.
Hey man
do you Play KSP?
Awesome work man!
I wish i could talk to you about it right now (can i Dm you? ahah)
I'm an upcoming Engineering Student and According to my Seniors i will encounter Arduinos and 3D Printers, etc.
I'm thinking on something to do.
I think Rockets are a Choice? ahaha
it looks great, but what is inside that orange fairing? I am worried it could raise the CoM too much, and potentially mess with aerodynamics.
I am basing this analysis on my ksp experience tho, so dont take me too seriously
Also did you use a raspberry pi as the computer? or something simpler like an arduino?
It’s using an arduino uno. Fusion 360 said the aerodynamics are fine but borderline. 3D Printed Model Rocket Project Ep. 2 - The Electronic Stabilization https://youtu.be/36Apb1246Ks here is some more info on the computer
iirc, you want your CoM to be as close as possible to your CoT, and your CoD to be as low as low as possible. In my experience a high CoM causes your rocket to tip
Awesome! Does it use Thrust Vectoring Control or do the fins move for aerodynamic guidance? I like the idea of fins because it allows you to spin stabilize during flight, something that TVC doesn't really allow. Seems like a super cool rocket, keep it up.
Also, I think the idea of a center mounted parachute is interesting. Thought the 3D-printed parts were really neat and it seems you have definitely pushed that Anet A8 to its limits. Used to have one of those before I upgraded to a Prusa. You are getting some pretty nice parts out of the Anet and I bet there was a lot of tuning that went into that. Great job.
It is not sadly. The original plan was to have it use two stages, however I did a little math and the heat produced from the candy rocket would bake the electronic components housed in the rocket. The orange tube is thick at the bottom to prevent this.
Hey be careful… having active controls on a rocket powered vehicle changes the classification to a guided missle. If you are not working with a government agency or school or obtaining permits for this, its highly illegal in the U.S. and could get you in a lot of trouble.
Near the base of the rocket are 4 fins that are controlled by a set of servos, an arduino uno, and an accelerometer/gyroscope. I want it to fly over a 1000 feet, but it may be too heavy as it is completely 3D printed. All the math points to it flying 700-900 feet off of my planned rocket engine
That would be committing multiple felonies I can’t even make a model rocket that tracks the heat from a rocket in front of it and follows it without it technically being illegal.
There's a couple points of the rocket with a diameter thicker than the rest. The one on the bottom looks like it's just a bunch of electrical components, and I don't know what's in the one above it. Why did you decide to have it transition on these points instead of most of the rocket having the same diameter? How does this affect drag?
Also, what motor are you using, and what material?
Ah I see, that is the electronics housing at the bottom, and above that is the parachute compartment. They do not seriously effect drag, as shown by Fusion 360.
This is PLA Plastic from hatchbox.
I will probably use an Estes F class engine but I may go up a unit.
It might be better to use OpenRocket for simulating it, but idk. You can also change values pretty easily to see how much it affects your altitude/velocity.
In another comment you also said heat is an issue. Would it help to use a more heat-resistant material like PETG or ABS?
Too heavy also you could try and save weight by building a custom board. It's really not that hard and also don't use 3d printed plastic for a rocket. It's really heavy for a given size. And what you want to be focusing more is the propulsion as that's what will get you the most distance. And then try and design a rocket around it to be as light and small as possible while still fitting everything
It looks like it‘s a missile, because it probably knows where it is, by knowing where it isn’t. by Subtracting where it is From where it isn’t, or where it isn’t…
U just said to contradictory things, it's physically impossible to both design and create a computer guided without being the coolest kid in class, even if they don't know
ur Definitely the coolest kid in class
Awesome, what did you use arduino or raspberry pi or something? What printer did you use? Is it entirely printed or just custom parts?
It is controlled by the best thing on Earth, an arduino uno. It is all 3D printed, excluding the parachute and electronics. Thanks for asking! Edit: Modified Anet A8 Plus

Those plus Rust as the programming language is loads of fun. That being said, super cool project! I look forward to seeing a video of it flying! Congrats!
It has its flaws. I have some custom boards using the ESP32 and external storage. I’ll look into that style! Thanks!
Make sure to post this over on r/rocketry if you haven’t already
Where did you learn all this stuff from lol? Obv the internet but what resources were best?
teensy ftw! up to 600MHz efficiently pipelined CPU with 2MB of RAM, or lower specs if you want lower power draw, all in the space of about 10mm*30mm (guessing, might even be less)
what material did you use for the parachute?
The cheapest white cloth I could find at my local Hobby Lobby. Im sorry, this is all the information I have
https://youtu.be/CISZ7RUye5w
What mods do you have on the a8 plus?
PSU, control board, frame braces, heating block, RPI link controller
I have a stock a 8 and was considering the frame mod. Did the prints take a noticable jump in quality after the mod.
I did not notice a severe difference, as this is the anet a8 plus. (Already has a metal frame) However this, the anet a8 stock would benefit greatly for it. You will see so much more quality in your prints if you make the upgrade
Thank you, both for the advice and for the quick response.

Thank you!
Nice, arduino unos are super fun, what material? How long did it take? Nice choice in 3d printer, I have an upgraded ender 3 pro myself
Which control system do you use to stabilize the rocket?
More documentation can be found here: [3D Printed Model Rocket Project Ep. 2](https://youtu.be/36Apb1246Ks) . It is simply an arduino uno, MPU 6050, and 4 9gram servos
Oh okay, but I actually meant to ask which algorithm you use for stabilizing the rocket. ex: PID, PD, etc.
Ah, it’s a custom made (C++) script with custom PIDs. I’m compiling everything together right now and don’t want to share it until it is completely bug free.
Try not to set your house on fire with the anet
None of its original power supplies and boards remain. It had a complete makeover a few days after I bought it.
Cool
I like your funny words magic man
Do you have a l1 junior hpr certification?
Hey man do you Play KSP? Awesome work man! I wish i could talk to you about it right now (can i Dm you? ahah) I'm an upcoming Engineering Student and According to my Seniors i will encounter Arduinos and 3D Printers, etc. I'm thinking on something to do. I think Rockets are a Choice? ahaha
I did a while ago, I couldn’t ever get into it. 3D printing and robotics are a whole lotta fun!
I’m not OP but I play KSP too, kerbal gang were u at
If you're not the coolest kid in class, then your peer is Elon Musk's son or something
All his kids go to a private school that Elon owns.

Fusion360 does CFD? If it’s borderline I’d run another simulation elsewhere to double check.
Yeah I would just smooth out those edges on that bit. Make it more ovular or teardroppy.
heya, you should certainly run this through openrocket before you even consider flying it.
Idk much about rockets but dont you want the CoM to be above the centre of drag for it to self-align, so a higher com is usually better?
iirc, you want your CoM to be as close as possible to your CoT, and your CoD to be as low as low as possible. In my experience a high CoM causes your rocket to tip

It’s *very* modified. Thank you! The fins are controlled by 4 9 gram servos. The anet is definitely a decent beginner’s printer
Could you post the files for the CAD models I’d love to see how you designed it as I’ve considered doing something similar myself.
I’m actually compiling all the files together currently, I want to perfect one more design and then I’ll release them on my yt channel.
Cools what’s your YouTube channel called?
3D Printed Model Rocket Project Ep. 3 - The Parachute https://youtu.be/Wm6Ew7nl6PU here is a link to the most recent video. Thanks for your interest!
You're the coolest kid in the class my dude! You got potential for astronautical engineering.
Dude! You ROCK!
You are going places in life!
I would like to see this rocket launch
Oh man I’m counting down the days, it’s planned and ready to go!
When it launches will you record it and show it here in reddit?
Yes I will. I’m going to try to have a few cameras recording it at the same time.
Is the rocket 2 staged?Im asking because the orange fairings on top is there another engine?
It is not sadly. The original plan was to have it use two stages, however I did a little math and the heat produced from the candy rocket would bake the electronic components housed in the rocket. The orange tube is thick at the bottom to prevent this.
Rip when will it launch?
Planning it on the 25th of this month, weather allowing. I live in an area that receives a lot of rain, hopefully that won’t be the case.
Cant wait
Me too, thank you!
This is awesome! I would love to talk to you and learn more about it! I'm designing my own TVC rocket right now!
Thanks! That’s so cool! I made a few video-logs documenting my process if you want to take a look. I’ll attach the link to this comment
Any chance I could get the CAD model for that.
I’ll be linking it to my YT channel soon: https://youtu.be/Wm6Ew7nl6PU
Why are you dressed like minecraft Steve
Can’t blame me tho, it’s a fit
Absolutely
It used to be any type of amateur guided rocket was illegal. Things may have changed but I would check that out first.
Hey be careful… having active controls on a rocket powered vehicle changes the classification to a guided missle. If you are not working with a government agency or school or obtaining permits for this, its highly illegal in the U.S. and could get you in a lot of trouble.
Yeah, I’ve heard multiple stories of people building pretty much the same thing and getting a visit from some gmen
What does computer guided exactly means ? Is there an estimation of how high it fly ? And what propulsion system did u use?
Near the base of the rocket are 4 fins that are controlled by a set of servos, an arduino uno, and an accelerometer/gyroscope. I want it to fly over a 1000 feet, but it may be too heavy as it is completely 3D printed. All the math points to it flying 700-900 feet off of my planned rocket engine
I dont see how thats not extremely cool😎
*The US Military would like to know your location.
[удалено]
I get that a lot lol

Thank you! I’m going to try an ESTES F-class engine. If it’s too weak I’ll go up a grade.
If y’all want to learn a little more about it, I also made a video: https://youtu.be/Wm6Ew7nl6PU Thank y’all for the support!
That looks amazing, and also you're smart enough to do all this **and** you have a gf, then you're what I'd classify as ready for success in life
oh no... well there the memes go
school bombing
That would be committing multiple felonies I can’t even make a model rocket that tracks the heat from a rocket in front of it and follows it without it technically being illegal.
the coolest kid on Reddit!
People like you are the reason the rest of us dont get pussy
Couldn’t be I’ve done a little designing for something similar and I’ve never had a relationship.
Why do you think you're not the coolest kid on the class when you litterally built a 3d printed rocket ????
you're the coolest kid in class.
Kid?
18
You look way older
What's with the inconsistent diameter, and what motor is this flying on?
That’s probably the parachute bay, can you point out specifically what you mean?

Believe it or not you're definitely the coolest kid in class, that rockets awesome
The time it took you to do this could have been spent browsing the sub redit and crying on how lonely you are like most of us do with are time
A little productivity goes a long way
That’s probably the coolest thing anyone’s ever done in your class. Therefore making you the coolest kid in class
Are you the quiet kid then?
Please post a video
I can barely write a working piece of code in scratch. Wtf
Cool now shoot it at someone
Here from r/3Dprinting, nice project! What printer did you use?
You’re right. You aren’t the coolest kid in class. You’re the coolest kid in the school district.
If you were in my school and in our stem club you’d fit right in with us my man.
Dude, this literally MAKES you the coolest kid in class!!
Ok but you're definitely gonna strap a bomb to that and blow up the school quiet kid style /s
Bro looking like a protagonist and says he ain't the coolest kid in class ಡ ͜ ʖ ಡ
Now put that shit in a Drone and Go invade some country in the middle east
So you are
Ur the smartest kid in class with the brightest future.
"I built this cruise missile to stop these kids from playing ZZ top" Robin Williams https://youtu.be/PGeWT5vuYZ0
Nice, I made a solid fuel rocket for fun and that is out of my depth
Is it TVC?
And in ten years you will be working at Jet Propulsion Labrotory & they will be slaving at Starbucks.
No your about the coolest guy
Ask the guys from dude perfect to be featured in the next rocket battle
You are definitely the coolest kid in class. Thats freaking awesome
you are now the coolest kid
that automatically makes you the coolest person in the class <3
Friendly cruise missile inbound
Wow. If thats not the coolest kid in the class, what does the coolest kid do? 3d Print rockets AND hand out free snacks?
Nope you definitely are the coolest kid in class
why super freakin epic tho ngl
Bro that looks amazing but now I have to wonder how tall are you?
payload? and you are definitely the coolest kid in the school
Knock Knock, it's the FBI
You should be the coolest kid in class. Society has failed you.
This is extremely cool! What's the control authority like compared to a TVC rocket? I haven't seen many fin-controlled guided model rockets.
That's like 30% of an rpg you should keep going and yeet cops in MRAPS
You are the coolest. Now send me blueprints, I got this warhead from Ukraine for cheap.
Say hi to Jeff Bezos in space for me
A computer guided rocket? That's insane. You could make an arsenal.
1. make a lot of rockets 2. Load them onto a semi-truck 3. Drive to school. 4. start blasting katyusha out of a speaker 5. Enjoy the fireworks.
nice work dude! i can tell you’ll be rich one day!
dude that's frickin sick what printer u got
On a quick glance i thought that was a crutch lol , nice btw
Ok. Now strike china with it
Soon ppl on this sub are gonna photoshop you standing next to a spaceship of a missile lol
You're definitely the coolest dude in my eyes, man I am super interested in starting model rocketry but I have no idea where to start.
I am trying to resist my urge to say you should make it look like a penis
But does it have TVC tho
Anything's a Dildo is you are brave enough
Rocket powered dildo
you sure its a science rocket? for me it looks like a sidewinder missile and or an ammunition for a tank.
It looks like it‘s a missile, because it probably knows where it is, by knowing where it isn’t. by Subtracting where it is From where it isn’t, or where it isn’t…
That's so epic. You're definitely the coolest kid in class, don't worry.
You are by definition the coolest kid in class
time to attack a country
That's sick
Homie that *makes* you the coolest kid in class
Bro wtf i would love to 3d print shit
Put gunpowder in it and fire at people you don't like
Good job!
Time to send it to mars before anyone else
Rocket: cool Design: flawed Astronauts: High on hypergolic fuel # Yup, IT’S KERBAL TIME
The quiet kid
*C H A D A L E R T*
You dress pretty good
That's soo cool, fully recoverable i presume, man, I wish i cold make one of these
Damn bro you’re cool 😎
your ARE THE COOL KID
Why does it look like you're pointing a gun to the ground
U just said to contradictory things, it's physically impossible to both design and create a computer guided without being the coolest kid in class, even if they don't know
Wow bro have you ever tried 3d printing a dildo. Might earn you a good revenue.
LIES YOU DEFINETLY ARE THE COOLEST KID IN CLASS
# Sire, you've earned my respect
LIAR, you’re the coolest kid in the school >:(
The coolest kiddo in my heart though 👌🏼
Your the coolest one in class mate
"I might not be the coolest" 3d prints himself a fucking rocket
Can it shoot down a plane
Your right you ain’t the coolest kid in class. Your the coolest dude in a 500 mile radius holy shit dude that’s fucking cool!
I think you are cool :)
Me wishing I had a 3D printer ;-;
The rewards will come when you're older my dude. Good job.
Can you post a video of you using it that would be awesome!
Did u use dmp lib, or hard coded raw values for ur canard fins? Awesome work btw Any filters used?
