World Record Gearbox (Approximate Ratio 1:10^220)

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.

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)
