Assembly

1. Stage 1 Carrier

When inserting the Stage 3 Planetary Gears, make sure the grooves on their shafts face outwards so they align with the small flanges inside the holes of the Stage 3 Planetary Carrier. Also insert the gears from the correct side into the carrier. The holes are conical.
Make sure the Stage 1 Planetary Gears are oriented correctly so that its teeth can interlock with the Stage 1 Sun Gear.

 

2. Stage 2 Carrier

Use the thicker one of both Planetary Carriers.
Insert the gears from the correct side into the carrier. The holes are conical. Make sure the grooves on their shafts face outwards so they align with the small flanges inside the holes. Be sure to insert the axles all the way, it can take quite some force sometimes.

 

3. Stage 3 Carrier

Use the thinner one of both Planetary Carriers.
Insert the gears from the correct side into the carrier. The holes are conical. Make sure the grooves on their shafts face outwards so they align with the small flanges inside the holes. Be sure to insert the axles all the way, it can take quite some force sometimes.

 

4. First Internal Subassembly

Use the longer one of both hex shafts.
Make sure the Lower Internal Toothing can fully close and the gears run smoothly.

 

5. Second Internal Subassembly

Use the shorter one of both hex shafts.
Make sure everything sits close together as shown in the picture.
Make sure the Upper Internal Toothing can fully close and the gears run smoothly.

 

6. Final Assembly

Make sure everything sits close together as shown in the picture.
Screw in the Lock Nut with the flanges facing outwards. The torque you can apply with your bare fingers is totally enough.
Slide on the Adapter all the way and make sure there is no gap larger than ca. 1mm between the Upper Housing and the Adapter.
Fixate the Adapter and screw on the Lower Housing.
Tip: A few drops of oil will make the gears run smoother. Especially any friction reduced on stage 3 can make a difference.

I spent so many hours printing this. And for whatever reason I just can't seem to get step 5 to work for me. If i put only the bottom 2 gears I can get it to click in place and spin smoothly. But the moment the top part is involved I can't get it to work, it's just completly stuck. Any tips?

When applying the internal toothing, twist the output shaft until the gears mesh. For me it can take up to 10 attempts of removing the internal toothing and putting it back on in another angle. If it still doesn't work for you, maybe check if all teeth came out cleanly and with no stringing inbetween.

Thanks for taking the time to reply. I've been trying for 2 hours now and my hands are starting to hurt :D. Everytime it works fine if i just put two of the gears, but when adding the third it just stops. Maybe I'm doing something wrong. Adding some photos of my gears, maybe you can see if I'm doing something wrong. I looked at the instructions many times :|

On the pictures everything just looks perfectly fine (Except maybe that one Planetary Axle wasn't inserted with the chamfered side first. But it won't affect the function). Have you checked the Internal Toothing as well?

Really great model. Instructions are very clear. The only part I had a bit of trouble on was the stage 1 assembly - I put the gears on upside down the first time and found that things wouldn't mesh together in the right place when trying to place the third gear. I used a small screw driver to pop out the pegs and put them back in the other direction and things worked well. I used a bit of the bambu lubricating grease on the gears to reduce friction but there's a bit of plastic squeaking still, so I will probably add more. I love how sturdy the launcher feels and how well it twists up to speed. The casing is comfortable in hand and going together without hardware is amazing! 1 Remix I'd like to see to the mounting peg that the propeller goes on: My 7 year old daughter has a hard time spinning the device up to speed quickly enough and the copter generally just lightly floats off and and then falls to the ground without going very far. I would love an alternative launching attach point that helps the copter stay on the launcher for longer. Maybe either by having an extended length launch point or some little gentle "catch" points on the grooves that require a light amount of force to push past so that the copter has to be spinning a bit faster before it will release from the launcher.

Hi, thank you for your elaborate comment. This genuinely helps me improve the model. I added the regarding hint to the assembly manual. I think the only realistic fix would be an extended adapter. How I see it, the gentle catch concept requires for a very consistent friction coefficient between the prop and the adapter and needs a quite gentle leaf spring that stays constistent as well. If 3D-printed, both things are great subject to wear, and if made from PLA to fatique as well. In my mind I havent come up with a potential solution for that yet😅

My 6 year old has the same experience; I wonder if some alternative blade designs could improve lift at the lower speeds our younglings hands can impart. One thing I did was told my son that this is a special design that is meant to fly more horizontal than the standard VTOL most of those pull style copters operate. So if he holds it at a 50ish degree angle it adds enough friction that it gets up to a high enough speed he can launch them clear across the room which he loves to do now, so he is more engaged with how far he can launch it, vs how high

Hello! I went ahead made a print profile that includes an extended adapter. However, I have not tested it yet as I still have the original design printing. You can go into the print profile and manually select the adapter only to print. (I extended it decently, but nothing too crazy.)

I need some help. I have everything assembled however I can not rotate it at all when fully assembled. If I take the top sleeve off I can rotate the two gear sections separately from each other but I noticed how the top part spins the other direction then the bottom part and they cannot physically rotate in the same direction. I don't know how this is possible as all the gears are perfectly aligned and they rotate very smoothly. And there is no other way I could possibly assemble this together without it not fitting together. I didn't change anything at all in the print profile for the a1 mini. Could this be a problem with the profile that it has one section of the gears inverted?

Hi, if a section of gears would be inverted, it couldn't fit into the internal toothing. Did you use PLA Basic, and flow dynamics calibration?

Replying to @LukasHannert :
Yes I did, perhaps for the gears I used PLA matt as it was the only red I had but the rest is basic. But the gears all turn fine. it doesn't seems like it's too tight or anything as I can squeeze one part of it and it turn just fine. But when both parts are held together like what happens when I put the top sleeve on it becomes physically inmoveable. However I can spin the gears when I twist the top part where the fans would fly off. Just not the bottom

Nevermind, It was just an extremely tight fit. After letting it sit sometime with WD40 and some excessive force it eventually started working and got smoother and smoother. I just didn't realize it would require that much force in the beginning

Gigant Launcher 125% German below! Hi Lukas - I truly could not resist - I had to give it a try. Here is the gigantic 125% version. With an adapter for the standard propeller. The gearbox runs as smoothly as silk. It is magnificent during launch. Truly a great deal of power! It took me a good 12 hours with two Bambu Labs. Assembly was incredibly easy. It worked flawlessly right away. I am absolutely thrilled. Such a fantastic project! You are a true master! Best regards from Berlin Folker German: Hi Lukas - ich konnte echt nicht widerstehen - ich musste das ausprobieren. Hier die Giganten Variante 125%. Mit Adapter für den Standard Propeller. Das Getriebe läuft butterweich. Es ist der Hammer beim Abschuss. Richtig viel Kraft! Mit zwei Bambus habe ich gute 12 Stunden gebraucht. Der Zusammenbau war super einfach. Es hat sofort funktioniert. Ich bin begeistert. So ein tolles Projekt! Du bist ein ganz großer Meister! Viele Grüße aus Berlin Folker

Indeed, the launcher now lies comfortably and firmly in the hand. For the large propellers, it is certainly the right launch ramp with a good grip. A true club. The thing is such a riot of fun. My long-time friend Ralf is a trained aircraft mechanic, who said 20 years ago that the younger generation no longer has any idea of ​​proper mechanics - that must now be seriously reconsidered! Damn it :)

I see you have several sizes, does the size of the launcher have a significant effect on how far it launches?

So I printed the white "Output Shaft" in 3 pieces since I couldn't complete step 5. Now when I turn from below and hold the lower part of the divided output shaft, the above two levels spin. If I hold the lower two parts and turn from below, only the top part spins fast. If I hold all three parts and I turn below, nothing spins, it is stuck. But it should spin because that is the behaviour when I put it in the black enclosure? Don't want to put it in because I am afraid I can't get it out anymore. Or is it ok to leave the top part of the output shaft out?

Hi, the gaps between the 3 internal toothing segments look concerning. Have you pushed all shafts all the way in? The top part of the output shaft (or "Adapter") can be left out for a spin test. Its only needed if you want to launch propellers.

Replying to @LukasHannert :
Thank you. Here is a photo of the gaps. I already tried to get them more in with a platic hammer, but it seems they don't want to come in more. Any tip to reduce the gaps? Edit: I could remove the top and so use more force. I will try again. But now don't have the time anymore. Will give an update! Edit2: Did a quick try. The gaps are gone, but it still locks if I include the top element. Would maybe more oil / WD 40 help?

Usually this is a K-Factor issue. But since many users are experiencing tolerance issues, I'm currently working on a version with more clearance.

the instructions are not correct. I did exactly as instructed and the first and second gear bottom part is shown in the assembly guide to have the “big hole” to the top but it’s actually to the bottom otherwise it can’t be assembled at the end to attach with the little sticks. correct? I just lost a whole lot of hours and material because I can’t get the pieces apart anymore. :(

I'm sorry to hear that. In this picture the larger diameter of the conical holes is facing upwards. And this is the correct side to mount the gears from. It's supposed to be quitea a tight fit. Also it shouldn't even be possible to insert the planetary gears with their axles from the other side.

Hi Lukas. The problem is actually the assembly between all 3 parts at the end - in your first photo, the big hole is up, then in the second, you actually flip the "triangle" piece - and only now after doing it all wrong I realize that - I hope I make sense? The real problem is the first picture to be "the other way around" for the triangle. (for both steps, 1 and 2 for the assembly)

Okay I got you. You're the first one to at least tell me this but I get that it's confusing. I was planning to redo the assembly instructions already so when I'm at it I will take care of the orientation issue. But did you actually manage to press the gears axles all the way in from the wrong side?

This is the most awesome toy design that I ever printed. Precise as hell and was easy to assembly. Hint for others: Use WD40. Looks fantastic, can't wait to try it out, the props are just printing now. Only drawback is that the wall thickness not aligns well with 0.4 nozzle so it was a lot of printing time, but worth it! :)

Nice, thank you for the review and the kudos! Very flattering! I have to say that most users won't agree with using WD-40 since it's not a lubricant and isn't made for long term use on plastics. It's made to displace water (hence the name).

Replying to @LukasHannert :
By default yes, but the list on my bottle is the following: displace water....etc.. and lubricant, cleaner. When I started to put things together it was stucked a bit and this helped a lot. Once this dry I will try silicone spray that will be even better maybe.

A few things that would be nice to do on this print is optimize the print speed for the outer shell so we don't get as many of the bad looking lines.. I am new to this hobby, but I have seen some videos in the past on how to overcome this, I thought I could play around with the in the slicer but I don't seem to know the right settings to adjust! I understand why it does it with the openings.. but how to stop it from this behavior.. I know there is a way another one I was as well thinking if the propellers can be printed in a stack so we can print many at a time.. like..as many as the bed can do almost, probably 9 stacks high of 9.. 81 at a time would be nice :D

Fancy idea with the prop stacking, I just wouldn't know how to seperate them cleanly. To solve the issue with faulty Z-alignment you could check your XY-belt tension and run the calibration program.

Very nice model. The print profile is perfect, all parts fits at first time, assemblies informations with pictures are simple as possible. Thanks for your work, my childrens and me have fun with this device ! I added a little oil, but it's not necessary, the mechanism is very smooth, with no adjustments to make.
