It would be interesting having a clutch mechanism to separate the power output and isolated from the engine.

That's pretty cool. This would be representative of a very compact transmission like might be found in a motorcycle or early FWD car. A typical rear drive manual transmission has the input and output shafts on the same axis, with the power being sent down to a countershaft to select the ratios. The lowest reduction is usually at the rear of the case, as it puts a huge load on the shafts trying to push apart rather than rotate. You'll have first, second, third, and sometimes fourth as reduction gears, with the next gear being a direct connection between the input and output shafts. After this, you have overdrive gears, where the output spins faster than the input. This is usually in a second section of the transmission, behind an intermediate bearing plate as now pushing forces are getting higher again.

Amazing! If I had to suggest an improvement, the color coding could be improved. Everything perpetually connected to the driveshaft should stay blue, but everything connected to the output shaft should be red, so we can see better what's connected to what. The rings could be their own color like purple or something

My favorite printed gearbox is the sequential 7 speed w reverse. Don't remember the designer but he did an excellent job. Its a good design as you can scale it with realitive ease depending on your application. When printed with nylon it is strong enough to stick into an rc car. All I have tried so far is an electric motor however I think it can handle nitro as long as it isnt too small.

I love how this video showed how simple a concept this is! So many other videos make it way more complicated

This is so beautifully explained and demonstrated. What a great video!

One of the best basic explanations I've ever seen. Simple and direct with great visuals. I agree with some of the other comments about the clutch mechanism but I understand that would be best done in a follow up video. Keep up the good work!

Thank you so much for the dedication to your videos and the quality of your videos. I enjoy them every time and i think you have some of the best quality descriptions in this sort of content area

Such a great video with a fantastic explanation, well done. Do you have this transmission available for download ? I think that it will be a great project for kids to learn how a transmission works in conjunction with your video and explanation. Keep up the great work

KZfaq is recommending this to me when i started working on my own 3D model of a manual transmision in cad which is scary and useful and btw you’re videos are awsome its a shame you dont get the support that you deserve

Genuinely one of the best demonstrations of how a manual transmission works I have seen yet. Better than those fancy 3D animations for sure. Only thing missing is a clutch.

I love them for how simple and straightforward they are, you couldn't be more basic and direct if you tried.

Soo cool man been here since 90k but love your videos, learning more about 3d printing and physics then I thought.

Awesome video! Helps a lot for a visual learner like myself, thank you for making this!!

Short, simple, amazing. Keep it up!

What a great explanation of this process. Thank you!

Very good info. Concise narrative and good camera work. Bravo!! Well done!

Is there a link to the stl? Would love to print this myself

I wish I could bring this into my classroom! What an awesome visual!

Thank you for demystifying such an ingenious mechanism

Honestly this is very helpful for learning how a manual transmission works

Good job explaining manual transmission. Thanks for sharing your design ❤

I love how you simplified a very complex engineering problem into something dummies like me can understand. very good and educational video!

Great video. Really helps me to understand. Thank you.

I’m basically building a go-kart from scratch and this is exactly what I needed to see

ive seen a bunch of these, but this one was the best

man, you explained it so good.

this video's on par with the old black and white demonstration video's from the 30's and 40's, nicely done.

That explains this really well. Would be interesting if you expanded and added a clutch disconnect too. Just to see the extra level that adds. The clutch is not needed to shift but it’s cool too see. Something I don’t know now is how the synchronizer works.

Linear boxes, like in motorcycle, are just as much fun. I love how the two systems both work great.

Nice and clear! Great video!

Great video. Thanks from Texas.

Beautiful work bro

Really cool. Thank-you!! I've always wanted to know

Great video and explanation

I was so intrested thankyou for explaining

This is friggen godly keep it up!

This is neat! Thanks for sharing

Amazing video and super simple to follow allong! Is there a way to get the files for it? Id love to print one out myself

Thank you, amazing video

Best explanation I've ever seen.

Man you are a real 3d printer I mean look at bro... That looks really awesome bro well made 👍

wow always wondered how they work nice vid

i love the 3d printed model of it that's awesome well done ♥

Really well done.

Excellent model, waiting for stl :)

Great explanation! Thank youi

Excellent explanation!

This is such a complicated way of explaining manual trasmission!

Thank you the video.

Super videos ! 👍

Awesome. Thanks!

Excellent video! I would love to see how an automatic transmission works if you haven't already done that.

Wow this is very very very good

This dramatically clarified how a transmission works to my chimp brain... thanks for the video!

So Cool. I Iove this.

I've been to a lot of these "How manual gearbox works" videos, and I understand how they work, but what I never understood is how the parts are assembled and how that relates to how it works

Is this model online somewhere for download?

It is Simply amazing

Super interesting 👍

Teaching me more than my engineering professors

Thanks for such a cool demonstration. It has always been a huge curiosity of mine, how gears are being shifted in a moving car...

Thats a cool little model. You should release the stl files so we can print one. I'd love to have this on my desk.

Wow thank you so much! So all the gears are always meshed together! The shift only connects one of the pairs to the output. It took this video for me to realize that the un connected gears were still spinning, just minding their own business at their own speed around the shaft. It’s an amazing design. I’d love to have that toy at home. Is it selling anywhere?

Man, that's some skill, shifting without the clutch 🥶

Thank you for the interesting video, where can I find this model?

Thats a fantastic little model! Is there a link to the stl files so people can make their own?

This is nice Work there! I Hope You Can Upload the 3d files so I can recreate your transmission!

The people that come up with with stuff are something else

Are the SDL available anywhere? Thank you

This is awesome

I would love too see you push it to the limits. I think it would be pretty cool to see how much load and RPM such 3D printed gearbox can handle. (and yes I will subscribe with notifications too see if you actually do it) :).

This direct connection between the wheels (via the output shaft) and the engine is why you can start a car with a manual transmission by pushing it (or as it starts to roll down a hill) and then popping the clutch (esp. in 1st or Rev) and then quickly pushing the clutch back in before it stalls again. I used to do this just for the heck of it in my driveway because it wasn't completely flat - I'd pop the clutch in reverse... never wore out my clutch either.

whats the gear generator program you are using? I need it for some future projects

great video but i was laughing when i read "do not put fingers in gears" and then you said "look what happens when i put my fingers in the gears"

Hello, I love the video but it would have been even better if you explained how the red circle transmits the mechanics power from the driveline to the ouptut. Have a great day :)

Super Cool!

I clicked on this video interested in this 3D printed mechanism and just learned how to drive a manual

Very cool.

That's a cool model

The text on the side of the model: "Do not put your fingers in the gears" 3D Printer Academy: *Puts fingers in the gears* 🤣 btw great content, thanks!

What program was used to make all the diagrams and editing?

Do you have a recommendation for a 3D printer that can do multiple colors without constantly changing filaments?

Can we have the files so we can try it out ourselves?

Great job you are genius 👍🌷🌹🌹💐💐

i felt like watching a commercial but actually learned something

nice demonstration now please do the same for automatic transmission

I would've loved to have this as a toy growing up.

very cool

"We have to shift gears to keep the RPM at a reasonable level." *laughs in rotary*

Ngl i really want that manual gearbox demonstration

A common trend in transmissions, these days, is a double-clutch multi-shaft transmission (sometimes known as a DSG). Would love to see a 3D-printed version of one of these.

Curious how many people watching this have ever actually driven a car with a *true* manual transmission, one with no computer involvement whatsoever. I learned on a '74 Toyota Corolla, with manual *everything*. Its clutch was incredibly unforgiving. If you were off in your timing by just a little tiny bit, the whole jalopy would start to seize, jerking the car forward and backward violently until the engine died. I have to say that learning on that beast made every other car, stick or not, I drove after that an utterly trivial undertaking!

Are you going to be adding this model to your website? Would love to buy the STL so we can make.

When you say “connected” does that mean the specified gears are touching and the rest are not but spinning freely?

Nice. Where can I get model data? I would like to build it.

Do you have a link to the model for this? Its beautifully designed!

wow perfect rev match.

That’s so cool! What was the print time?

The 3rd gear also represents an overdrive ratio. The output shaft turns faster than the input.
