I can remember shooting off Estes rockets when I was 10-12 a lot. We used to take note wind direction and speed. Tilt take off pole into wind accordingly. That way we didn’t have to go chasing after it when chute carried it. Brought back memories. Thank You
This was so much better than all these printer unboxing and reviews of 2020 from all the channels out there. This is how an adult looks like if he forgets for some seconds that he is an adult, lot of fun.
As someone who has been flying rockets for over 20 years, and started 3D printing nosecones and fin cans almost a year ago. I knew it would fly, if the CP CG is in proper positions. It look really awesome. Part of the reason you broke a fin was because that parachute was a bit small for the weight/mass of your rocket. You need a larger parachute for next time. Happy Holidays!
It was a blast and everyone had a fun time out there. It was a bit cold, so most of the family went inside the card to keep warm while David and I ran to get the rocket.
When I was younger I built a model once called a mosquito that is supposed to take a "A" engine but I managed to fit it with a long burn "B" engine , painted it florescent orange and woosh off it went never to be seen again...lol
Brought a tear to my eye thinking about my grammar school Estes rockets days. I designed and built an electric launcher with a selector switch that could launch up to six rockets one at a time (I was a nerd at a very young age). We used it a a launch day party one Saturday inviting our parents. The moms freaked out because they thought we were just building models! They had no Idea but calmed down when they saw our safety procedures.
Brings back memories. I’ve got two Estes rockets in the garage. They’ve been with me every move since I moved out of my parents house, many years ago. I also built a launch console like your Dad did. Thanks for sharing!
Way cool! I used to do model rockets as a kid..Then got back into it(called a BAR- Born Again Rocketeer) and started doing some really big, and bigger ones..I at one point launched a 20' tall rocket to just a little over a mile high! It was epic! I need to get back into it, I have enough kits(sheesh), but I have too darn many hobbies..3D Printing, beer brewing, painting and trying to find the time to work on building an airplane..LOL...Thanks for the great entertainment, Joel! It was a blast(literally!)
@@3DPrintingNerd And a different color. Sky blue and white makes it harder to spot I guess. Also maybe print the tail in one piece with an FDM printer. Polypropylene might withstand the impact better.
Please give Sean (Shawn?) a raise for knowing how to actually say "noir." Although hearing you say "no-arr" makes me think of a pirate toddler, which is an Image I thought you'd enjoy. Also, thank you so much for posting a happy, entertaining video on a day that's had a lot of stress for me. You've made my day better.
the yellow part on the end of the key is a launch rail safety. it used by put it on top of the launch rail when setting up the rocket so the rocket doesnt accidently launch while someone is close to it (say a kid hitting the buttons or something) by keeping the key separate from the launch controller during the set up procedure. also makes sure theres no electrical connection between the two and the flag on it notifies people that the rocket is not ready to fire yet.
Hi Joel Me and my uncle and dad go and launch model rockets together. I have 8 model rockets 🚀. And you are wrapping the parachute 🪂 right. I have the same pad and controller. And your rocket is considered a mid power rocket
This is on my list to do after my next animatronic. Only difference is I was going to attempt to print the body using Spiral vase mode to keep it light :) Excellent video! Definitely one of your top ones this year. And yes I did catch Sean leaving the half second clip of you removing supports and cracking the tail fin. I could feel the swear words leaving your mount a second later ;) Well done!
YEAH HE DID. Glad you saw that. I had printed 4 of them just in case. That fin ended up not being used. I had a BLAST making this video, this was a ton of fun, and it reminded me of the launches I had as a kid. You should definitely do this :)
So crazy high schooler idea(I did this with friends). Skip the parachute. Glue on the nose cone. Add a small hole below that in the side for the gas to vent. Cover the outside of the white tube with CA and accelerator. Launch...and run. Also suggest painting the cone so you can see it better.
Really cool! I built rockets for the Team America Rocketry Challenge about 4 years ago in highschool. I used our schools MakerBot 5th Gen and MakerBot Mini to make the nose cone, tube transitions, altimeter compartment and weight chambers. I've never thought to use the resin printer before for this application!
@@3DPrintingNerd and actually now that I think about it the engine you used was the same one we tried in our rocket. The altimeter showed about 1200ft and that was with a rocket taller and heavier than yours so I wouldn't be surprised if yours made it to 1800ft.
DUDE no idea you were into Rocketry! rocketry is WHY I got into 3D printing. I make entire rockets out of PLA and Paper Body Tubes. I will have to send you a kit!
I still remember launching model rockets with your dad when we lived in Colorado! He let me use one of his rockets fro my Aerospace Education class field day, and it went higher than any of the others. Unfortunately, when the parachute popped, the wind carried it into a nearby housing development, and we never saw it again. :-(
I got into 3D printing to feed the hobby rocket addiction. Little did I know 3D printing was a hobby unto itself. More rockets! Also, rocketry wants you back, Joel!
There are a few rocketry clubs in your area, Washington Aerospace Club, Oregon Rocketry, Tri-Cities Rocketeers, for example. I fly high power rockets with Oregon Rocketry. You should come out and see what fun we have, once things open back up!
I did model rocks a couple of decades ago with my dad. The rockets were much smaller than that one though. I've done water and baking soda / vinegar propelled rockets too.
My kiddos recently got interested in space so ive 3d printed some rockets and engines tubes and im going to teach them some chemistry at the same time making our own engines its so much fun and they enjoy it so much. this video was awesome
The paper tubes are called body tube or "the airframe" And yes its a launch rod. the purpose is to allow the rocket to achieve enough velocity so the fins can start working. these rockets have no "active" stabilization (thrust vector control ie engine gimballing or RCS thrusters or active moving fins) its "passive" guidance. so it needs a minimum airspeed for the fins to start working. that is what the launch rod or launch rail does. allow it to gain enough speed before its set free. To see some AMAZING things in model rocket check out Joe Barnard BPS Space. it is actually making 3d printed mounts for active gimballed model rocket motors!! truly amazing stuff. I am actually surprised the resin can handle the heat from the motor! impressive. I will be amazed if those fins hold up on landing. I am also amazed that the eyelet on the nose cone can hold up to that. I would use 4 or 5 times body length for just elastic shock cord.
I think the yellow thing on the controller is a cap to put on your launch rod so 1. you don't poke your eye out, and 2. the key is attached so you know the key is not on the launch controller while you insert the igniter.
Joel you should print up more model rockets as your side hobby with your kids... Thank you for sharing that epic launch and recovery .. Happy holidays to you and yours ..
Thank you! I know balsa wood is typically because of weight - but I think with 3d printing, the customization options go beyond what balsa wood can do. I'm excited to do this again.
@@3DPrintingNerd I have a few rocket kits, some built 20 years ago, never flown, but things like nose cones, fins, etc all could be home brew by rocketeers. See how it goes with the next one, mini Joel in space with a camera?
Great vid Joel. Made me reminisce on my childhood as well. Next time print the whole fuselage too! And of course, now I got squirreled and want to print a rocket. Ugh..... lol
As a rocketry enthusiast my self i found this pretty cool. Though I've built way more complicated rockets using GPS telemetry and altimeter to control parachute deployment, currently prototyping a liquid rocket motor running on ethanol and liquid oxygen, gj joel
That looked like fun. The rocket is big enough that you would be able to create a data logger (an esp32 or arduino nano along with a camera and some other sensors) and you could log the height, acceleration and speed and get a camera view from the rocket back to the earth.
you seen that holiday show ROCKET AROUND CHRISTMAS TREE where they make rockets out of xmas trees , snowmen and other christmas stuff its funny and fun
Nice video and an impressive rocket. I used large spray can bottles, like the ones you'll find in a barder shop or other professional use. You can rework them easily. They're very strong and light weight. You can find something like 60cm (23 - 24 inch) long and up to 7 or 8cm wide (approx. 3 inches). They're made of metal (alu) so they don't burn. Attaching the fins is however not that easy but it's doable. Give it a try !
I've actually been to 60 acres to launch rockets before and I swear I recognized where you were when I saw the thumbnail pretty surreal and cool to see a place I've been quite a few time in a youtube video
A couple of points, you should definitely attach the the body tube to the fin can with some sort of fixing, small screws or plastic rivets otherwise when the ejection charge goes off you risk the rocket splitting at ether end and not getting a parachute deploy. From a longevity point of view you might want to consider designing the motor mount so that you can glue in a cardboard tube for the motor to sit in. The exterior casing of the motors can get pretty hot and i have seen 3d printed motor mounts go a little melty! I don't have a resin printer myself so can't say for sure but from what i have seen and experience with 3d printing rocket parts you might find FDM printed rocket parts more durable, Or SLS if you have access to it!
I’m working on a project with 5th grade students. All students are designing and 3D printing a rocket to fly. We will design, print, make and then fly over 100 rockets.
I did much rocketry as a kid but sadly most fields of decent size quickly disappeared to become strip malls or housing developments as I got older. Some of my favorites would use spinning blades to slow the return trip to the ground or release gliders (one looked like an F14) which one would then have to chase down. In the end I was utilizing a cow pasture, but the last three rockets I flew all wanted to land right in the middle of a cow pond, no matter which spot on the field I launched them from.
Just watched the flight. fin broke as expected. resin is a bit brittle. Couple of suggestions. Attach the shock cord to the REAR of the model and have it run up the OUTSIDE of the tube into the top. this will cause it to come down top first or at least sideways. so the top hits the ground first instead of the fins. ALSO how is the eyelet on the nose cone? any signs of stressing or cracks? The body tube should be fine to reuse. if there is any zippering (like the shock cord tried to slice through it) you need more shock cord. I can also show you how to accordion fold the shock cord. Fold it up like an extension cord and use a small piece of masking take at each fold at each end. when its ejected the force will unfold and tear each of those pieces of masking take but each time it tears one energy is dissipated so by the time its done there is not enough energy left to rip apart or damage your model. Second notice the burning on the fins? that is the deflection off the blast plate of the launcher. need to use a stand off to lift the rocket rocket higher up the rod so that blast of initial flame does not torch your fins. you can also slap a little aluminum foil on them. it will blow off on lift off but might provide some heat protection for that first 1/2 second before it clears the rod. Also I am curious to see how the MMT the motor mount tube (the part of the fin can that holds the motor) held up to the heat.! Any deformation? ie where it looks like it got soft and shifted or warped slightly? I am curious as to how well that section held up. ALSO estes has a wee little tiny altimeter has a little lcd screen on it and everything. you pop that in their (attach to shock cord) and it will tell you how high the rocket went!
I'm IMPRESSED!!!! I think a larger chute would have kept the fin from breaking. The resin parts alone are probably far heavier than an entire rocket that size would be with the standard plastic/balsa/bass wood parts. So a 24" chute or a pair of 18's would probably serve better. You would of course have a longer descent, and with equal wind you'd have a longer drift and larger recovery area. Also I'm taken aback by the altitude!!!!! It looked in the vid like the landing point was AT LEAST 500 feet away. When I was launching C and D rockets, they never landed more than 200 feet away, and I doubt they went more than 250 to 300 feet. I only ever lost one rocket which was a very small A engine affair with a balsa nose and fins, I built it on a Friday night, launched it Saturday morning, and once it went up I lost track of it and never saw it again. And that round yellow thing that came with the launch controller that you couldn't figure out what it was? Safety cap for the launch rod because without it... "YOU'LL POKE YOUR EYE OUT, KID!!!!!" By the way, if you don't know about it, Google, "KERBAL SPACE PROGRAM".
I think you're right. Bigger or dual 18s would have been better. Oh, and yes these were heavier than balsa wood for sure. We had an absolute blast, and my guess is it was 800 feet in the air. Thankfully we didn't have much wind.
Print a different fin design that doesn't protrude from behind the bottom it will significantly reduce the probability of fin breaking. Also for a rocket that size you can go with smaller fins that will also have less drag.
Just a few of gripes. For potential to use larger motors, maybe go with a 38 mm, then choose to adapt to 29mm, also don't include a top engine block in the motor mount, as mid power motors that use composite propellant use a thrust ring on the bottom of the motor to retain it from going upwards. I feel like your nose cone shoulder ( the part that actually fits into the airframe to hold it on) is too short. Fins however were excellent, you chose a through the wall setup which is great. Also, why no follow footage of the flight. That helps bring you to the actual moment a little bit like you're also there to watch it fly. Well, these are just the arrogant nit picks of a Rocketeer or "enthusiast". Great video and good job on that rocket. I wish i could afford a 3d printer of my own.
So when are you going to 3D print the TIE Fighter fin can? Thanks for sharing, I used to fly a lot of rockets as a kid, and now have gotten back into the hobby, they are a lot bigger and louder. 3D printing has sure changed the game as far as building parts for custom rockets. I hope to see you do a lot more!
Very cool! I think fdm printing would be a better method for the fins. Abs or petg. Try it again with a small pen camera attached to the rocket! That would be some beautiful footage!
cool rocket, just need reattach-able fins. i would think that resin printing would be the wrong durability material. even abs 'like' resins are quite brittle. anyways looks like a lot of fun!
Are we going to see more rocketry from you? Clearly it's a cherished hobby and you could do a lot of neat things with a printer and your experience in it- maybe even a series on printed nozzles for water rockets?
Ah yes, model rockets. "smells like rocket" was one of my favorite smells. Also, I stuck some to a model car once. Went real fast before it was a melted ball of plastic lol.
I 3d printed a rocket have not tried to launch it yet. I was into building and launching rockets as a kid as well. But I always called the motor as you say a engine.
I wish I could have seen this video years ago, not because of the rocket or anything, even though it was cool, but because I have spent so much time sanding and cutting resin prints with out a mask oh dear.
It looks as though a larger parachute with a small hole in the middle would keep things intact to land safely and reuse. Assuming the internal resin is ok!
AWESOME video! I wonder if a FDM printer would be capable of printing these parts? Is the resin material more heat resistant than the traditional filaments? I'd LOVE to try printing some for my nephews, but fear that I'd have a fireball when the material I printed it with caught fire!
Hmm. The amount of heat is a lot, but the time the parts are exposed to it is minimal. I think a lot of people use 3d printed parts for rockets. You could use a toilet paper cardboard tube, add in the 3d printed parts like nose cone, fins, motor container, and fly it!
David, Rocket Retriever of the year! Pretty cool project Joel!
Hey, I love your aerospike video.
U guys should check out Sam Rogers RUclips channel on resin rocket. He's got some amazing stuff

That was pretty cool. Haven't done any rocketry in 25+ years. You clearly love what you do, Joel. Keep it up!
Thanks as always, man!
8:55 you snapped that bad boi didn't you
lmao! he totally did!
Looks like the exact spot where one wing broke in the landing too. Design failure or superglue to make the vid?
should have just printed another.
Sure did! We printed four for this exact reason. 😂😂
hahahah GOOD EYES. Sean left that in as an Easter Egg. I printed four, just in case and didn't use the cracked one :)
This was so much better than all these printer unboxing and reviews of 2020 from all the channels out there. This is how an adult looks like if he forgets for some seconds that he is an adult, lot of fun.
I would do this all darn day every day if I could!
@@3DPrintingNerd Make it a weekly thing. Have fun with 3D Printing :-)
You should do a part 2 and add a Accelerometer / Altitude sensors so you can figure out how high and fast it went.
As someone who has been flying rockets for over 20 years, and started 3D printing nosecones and fin cans almost a year ago. I knew it would fly, if the CP CG is in proper positions.
It look really awesome.
Part of the reason you broke a fin was because that parachute was a bit small for the weight/mass of your rocket. You need a larger parachute for next time.

Second notice the burning on the fins? that is the deflection off the blast plate of the launcher. need to use a stand off to lift the rocket rocket higher up the rod so that blast of initial flame does not torch your fins. you can also slap a little aluminum foil on them. it will blow off on lift off but might provide some heat protection for that first 1/2 second before it clears the rod.
Also I am curious to see how the MMT the motor mount tube (the part of the fin can that holds the motor) held up to the heat.! Any deformation? ie where it looks like it got soft and shifted or warped slightly? I am curious as to how well that section held up.
ALSO estes has a wee little tiny altimeter has a little lcd screen on it and everything. you pop that in their (attach to shock cord) and it will tell you how high the rocket went!
I'm IMPRESSED!!!! I think a larger chute would have kept the fin from breaking. The resin parts alone are probably far heavier than an entire rocket that size would be with the standard plastic/balsa/bass wood parts. So a 24" chute or a pair of 18's would probably serve better. You would of course have a longer descent, and with equal wind you'd have a longer drift and larger recovery area. Also I'm taken aback by the altitude!!!!! It looked in the vid like the landing point was AT LEAST 500 feet away. When I was launching C and D rockets, they never landed more than 200 feet away, and I doubt they went more than 250 to 300 feet. I only ever lost one rocket which was a very small A engine affair with a balsa nose and fins, I built it on a Friday night, launched it Saturday morning, and once it went up I lost track of it and never saw it again. And that round yellow thing that came with the launch controller that you couldn't figure out what it was? Safety cap for the launch rod because without it... "YOU'LL POKE YOUR EYE OUT, KID!!!!!" By the way, if you don't know about it, Google, "KERBAL SPACE PROGRAM".
I think you're right. Bigger or dual 18s would have been better. Oh, and yes these were heavier than balsa wood for sure. We had an absolute blast, and my guess is it was 800 feet in the air. Thankfully we didn't have much wind.
Great video Joel!! Worth watching just for your return to childhood like excitement!! 😀
He's a rocket man!!!! This is so good. It reminds me of childhood too. Needs to builds me one. Hoping fdm is up to the task.
Print a different fin design that doesn't protrude from behind the bottom it will significantly reduce the probability of fin breaking. Also for a rocket that size you can go with smaller fins that will also have less drag.
Just a few of gripes. For potential to use larger motors, maybe go with a 38 mm, then choose to adapt to 29mm, also don't include a top engine block in the motor mount, as mid power motors that use composite propellant use a thrust ring on the bottom of the motor to retain it from going upwards. I feel like your nose cone shoulder ( the part that actually fits into the airframe to hold it on) is too short. Fins however were excellent, you chose a through the wall setup which is great. Also, why no follow footage of the flight. That helps bring you to the actual moment a little bit like you're also there to watch it fly. Well, these are just the arrogant nit picks of a Rocketeer or "enthusiast". Great video and good job on that rocket. I wish i could afford a 3d printer of my own.
totally awesome! reminded me of my rocket teen years!!
great job joel and fantastic job david and crew
That tardis hoodie is so cool
So when are you going to 3D print the TIE Fighter fin can? Thanks for sharing, I used to fly a lot of rockets as a kid, and now have gotten back into the hobby, they are a lot bigger and louder. 3D printing has sure changed the game as far as building parts for custom rockets. I hope to see you do a lot more!
Rockets are very cool, no doubt about it... Love the video buddy
Thanks a ton! We had a blast making it!
Very cool! I think fdm printing would be a better method for the fins. Abs or petg. Try it again with a small pen camera attached to the rocket! That would be some beautiful footage!
That's was pure enjoyment! Thanks for the great video
Thank YOU for watching it! Glad you liked it!
cool rocket, just need reattach-able fins. i would think that resin printing would be the wrong durability material. even abs 'like' resins are quite brittle. anyways looks like a lot of fun!
Are we going to see more rocketry from you? Clearly it's a cherished hobby and you could do a lot of neat things with a printer and your experience in it- maybe even a series on printed nozzles for water rockets?
The day we can print metal rocket parts at home will be glorious.
I'll need some bigger engines :)
Reminds me of the time my son and I printed fins and nose cone for his water pressure rocket.
Wow. I didn't know the engines weren't cardboard any more. Science!
Fantastic job 👏 👍 👌.
Thank you! Cheers!
A fellow model rocket nerd, awesome
That’s awesome, but would this work on an FDM printer?
I just remembered David told me you have a RUclips channel in 3rd grade.
Btw I used to be his classmate in 3rd grade.
Ah yes, model rockets. "smells like rocket" was one of my favorite smells. Also, I stuck some to a model car once. Went real fast before it was a melted ball of plastic lol.
Great video Joel!
15:18 That’s the smell of freedom son!

I 3d printed a rocket have not tried to launch it yet. I was into building and launching rockets as a kid as well. But I always called the motor as you say a engine.
Super fun.
Dude! that's awesome!
It was! :)
I wish I could have seen this video years ago, not because of the rocket or anything, even though it was cool, but because I have spent so much time sanding and cutting resin prints with out a mask oh dear.
What other materials can be used for 3d printing model rockets?
3d print your tie fighter rocket and away you GO!!
nice work , just missed the parachute landing
Seemed so fun!
Thank you for another great video.
Glad you enjoyed it!
It looks as though a larger parachute with a small hole in the middle would keep things intact to land safely and reuse. Assuming the internal resin is ok!
Elastic is somewhat frowned upon, we typically use kevlar cord for its strength.
Nice to see some different content :) Stay safe Joel
Joel yelling “yeah!” At launch will be made in to a meme in 3....2....1...
AWESOME video! I wonder if a FDM printer would be capable of printing these parts? Is the resin material more heat resistant than the traditional filaments? I'd LOVE to try printing some for my nephews, but fear that I'd have a fireball when the material I printed it with caught fire!
Hmm. The amount of heat is a lot, but the time the parts are exposed to it is minimal. I think a lot of people use 3d printed parts for rockets. You could use a toilet paper cardboard tube, add in the 3d printed parts like nose cone, fins, motor container, and fly it!
@@3DPrintingNerd IF I can overcome the issues the CR6-SE is having, I may give this a go. My nephews would LOVE to participate in something like this!
