Description

update:

-Added an alternative base plate for wall mounting
-Improved base plate's holes tolerance for tighter connection with screws

-No need to manually adjust axles, gear mounts now have a single hole instead of a “rail”

Highest ratio gearbox ever created! (until someone prints an extra gear)

Yes, the universe will literally die (heat death) before the final gear will even start to move, in fact, the amount of time it would take the final gear to complete a single turn is like, 100000…(a lot of zeros) times all time that ever was and ever will be, from the big bang to the end of the universe (you can do the math).

It is incomprehensible as it is useless.

_____________________________________________________________________________________________

parts:

-Gear 12T-120T: 219 gears

-Gear 22T-120T: 2 gears

-Final gear: 1 gear

-49cm long, 5mm diameter aluminum rod (or any stiff material): 6 rods

-M5 20-30mm Screws: 10 screws

-Glue: 1 unit of glue

_____________________________________________________________________________________________

instructions (I mean, if you're crazy enough to print it)

Pretty straight forward, I added in the photos a top down view so you can see how many gears each "column" has, where to place the lower ratio gears and what spacers to put on each axle (feel free to add 1 mm spacers for different tolerance printers), after placing all of the gears on the axles, slide into the side gear mounts (you can either glue or not glue the two parts), glue the base plate together and screw both sides to the base plate (you don't have to glue the base plate together, but it is recommended)

Size: 50L*38W*13H (cm)

Done! Most useless, but most awesome thing I’ve printed so far (and I don’t see it ever getting beaten!)!

The designer has replied

@B4mb0T4b

it turned out super nice! thank you for your kind words 😁

@LucasDynamics

I will beat you soon! I have a YouTube video planned in which I will build a gear reduction of about 10(^270) with worm gears...

@B4mb0T4b

awesome! send a link once uploaded!

@revorc

I asked ChatGPT what would happen if you spun it the other was a 1rps it would break the speed of light. if you went the intended way it would not spin for the whole existense of the universe. so did this guy just make a black hole lol. jk I know that’s not how that works. ;)

@user_4203872167

naw instead he made a really inefficient light bulb lol.

@Davlumbaz

"1rps it would break the speed of light" must be the understatement of the year :D

@Air360Studio

🌌 Age of the Universe The age of the observable universe is estimated to be around: 1.38 x 10^10 🧠 Interpretation: 10^220 seconds is about 2.3×10^220 times the age of the universe. That’s a number so large that it dwarfs almost anything in physics, astronomy, or cosmology. Even the estimated number of atoms in the observable universe is only around 10^80 — which is still over 100 orders of magnitude smaller than this. 🧮 Bottom Line: 10^220 seconds is an unfathomably large amount of time — vastly longer than the entire history of the universe multiplied by itself trillions of times.

that’s ai generated for sure

Why did I print this? Just... why? Because I can. Fun fact, the smallest possible unit of movement in the universe is the Planck Length, 1.6e-35 meters. Given each gear steps down 10 to 1, after 35 or 36 gears, it is physically impossible for anything to move. The universe itself forbids it. This is the most pointless print I've ever done. I love it!

The designer has replied

@B4mb0T4b

love the color of the gears and cool fact, thank you!

@Dutch_Holland

what no...

@Hyperfin06

Bro, I’ve wanted to know that fact forever.

Some people said it couldn't be done, but here I am to prove them wrong.

The designer has replied

@B4mb0T4b

looks great! unfortunately, it seems like your assistant died waiting for the gears to print.

@bryan.rhame

Replying to @B4mb0T4b :

How much filament does this need?

@thecodedemon

Replying to @bryan.rhame :

I used two printers in tandem for all the gears, but it was probably just about two spools total, maybe a little more

I don't plan on printing ever, this is amazing design.

The designer has replied

@B4mb0T4b

appreciate it boss

@JS1980

Love it dude. I saw the guy who originally made this out of steel (I think). It's definitely a conversation starter. Are you mounting it to the wall? Does it have a motor?

The designer has replied

@B4mb0T4b

thanks! I was thinking of making a glass frame for it, mount it on the wall and glue some signs to the glass above the gears marking events like the death of earth, death of the sun, death of the galaxy etc.. like an exhibit in a museum. I thought about adding a motor but then it will have to have a wire dangling so I might add a small solar panel and an on/off switch so it can be wireless in the future and work for demonstration.

@user_2262457157

Replying to @B4mb0T4b :

This is a superb project, but no motor can operate it correctly; the torque required to drive such an assembly is quite high due to friction Moreover, the plastic will not withstand the stress either A static design within a framework remains the optimal solution
