- Accessory part for all axles and center differential. Replace the differential gears with this piece and you get a locked differential.
As usual you can find the parts on my youmagine account:

It would be cool if you could implement an electronic locking mechanism capable of being activated from remote control, this way you could have open diff for turns, and fully locked diff when you need it.
you should make a replica of the mercedes benz g63 6x6 amg that would be awesome
It just keeps getting better and better. Awesome job, keep it up.
Thanks! :)
cool as hell man keep it going man
I am crying man you are my role model
Great editing and captions.
Sooo awsome. How mutch cost the material for a truck?
Cuuute cabin !!!!!
just a thought, could you put a gear on a fork on a servo to disconect the 4x4 on the fly? i could see that helping with the immersion and it looked like you were enjoying doing donuts in your earlier vids
It's definitely possible but would require an entirely different center differential.
Veri good ! Locked rule !
Amazing👍
What kind of grease do you use? I tried petroleum jelly, but it makes everything stick. Nothing seems safe for PLA
Lithium based usually works good.
I mostly use a cheap no-name lithium grease for car wheel bearings.
It's sticky on the gears but makes sure you don't get plastic-on-plastic contact which keeps it alive longer.
that was a nice video.
The quick release cab needs rockets for more action!
I agree, I'll get right on that good sir!
Good. I'm waiting for results.
thz bro for your help
ESPERMACULAR!!! = ESPECTACULAR X 100!!!!
Quisiera saber que piezas hay que tener de repuesto, como por ejemplo, ir al parque y por si necesita mantenimiento, que partes son las que mas necesitaste hacer recambio, desde ya gracias. muchas gracias!
Thank you! Sorry for extremely late response.
An assortment of screws, an extra set of the axle internals(small diff gears etc) and maybe a few driveshafts.
That's usually what breaks.
how well does the system you created here work on concrete? im trying to build a rally car
I'm not sure what you mean by how well it works?
Durability? Grip? Handling? :)
No entendí nada pero me gustó.
Awesome overall design. For that alone I have just subscribed. Does your transfer case allow you to switch between 2nd and 4wd?
Thank you!
That's a feature I wanted to have but the project was already pushing my skills so opted to not spend even more time on implementing something like that.
Ideally I'd want 2wd/4wd and lock/unlockable diffs but haven't had time to dive deeper into finding a solution for it.
Need a cab lock too!
awesoeme and inspiring
Thanks!
torsen differential can solve the problem it allows different rotating speeds like normal differential but if one wheel loses grip it will automatically lock himself until both wheels get some grip but i don't now how to 3D printed :/
what 3d printer can I use for a project like that? tell me the cheapest possible, but that can print something like that pleaseeee
Any 3D printer with a build volume of 20x20x20 cm will be able to print this project. If you want something cheap, look for a I3 clone like Wanhao duplicator I3 or similar.
BE AWARE that cheap machines often have issues and require a lot of tinkering.
3D printing in general can be a lot of work, just to keep it working.
Mr.Crankyface thanks man, very helpful
why not use a torsion diff?? tight turning and no slip!
A torsen diff would indeed be way superior but also very complex to make at this scale.
Maybe sometime in the future I'll see if I can design one.
how much 3d printer
Can you please share the stls please I really love ❤ it
i am going to make a truck using 8x8 axles and your central diffential
It will work as a differential and it will avoid the power loss
The downside of a torsen style differential is that it, as far as I've researched, will still act like an open differential if a wheel lifts.
Hence it doesn't improve the off-road performance where the ground is so uneven that wheels will get stuck in the air or have extremely little traction.
+Mr.Crankyface exactly.... Try electronically adjust the the differential lock... Or try smart differential lock.... Btw try upgrading your single speed gearbox with 4 speed gearbox.. For more spees
once this project is done, make a drag car.
do you have the square part on thingiverse which u put in differential
Here it is: www.thingiverse.com/thing:1733143
where do you buy the printer machine?
I bought parts from Ebay and built my machine from scratch but you can find prebuilt and kits as well.
Mr.Crankyface ok thanks:D
music at the end please
Replacement of open differentials is the logical next step in the development of this project. But locked differentials is too rough and simple for project like this. You can try Torsen (it's can be simple: th-cam.com/video/osKLMzYxyyw/w-d-xo.html ) on both diffs. Or you can use open center diff with bigger torque in rear axle (it's pretty simple: th-cam.com/video/MjaCbpw84kw/w-d-xo.htmlm53s ).
Thank you for the videos! The Lego one should be replicable on a printer. Gives me something to work with.
here is another lego solution that you might be able to adapt?

Як мелодія називається
How much price ???
Can you make bus chases
Man try torsional differential system...
Wouldn't it be simpler if you would print a solid gear that has the same dimensions ( and shaft connectors) as the differential?
This is no longer a differential after all.
That depends on how you look at it I guess.
The pros as I see it:
-It's a very quick print(~15min].
-It uses extremely little filament because the pieces are small.
-The parts are very easy to print.
-The same part will work for any axle/differential housing on the V3 truck.
I think these pros outweigh any cons compared to reprinting the gear and shafts for every different variation.
+Mr.Crankyface I agree, but with that last one especially
I agree with Mortern. If you are going to permanently lock a differential, it's not a differential. You can turn it into a partial slip differential by adding a compression spring or torsion bar to the inside of the differential instead so it still works as a differential.
any possible chances of a car body
or a way to lower it?
I've thought about doing a pickup body or something like that, the scale wouldn't be 1:14 anymore but not everyone cares about that.
You can lower and raise it by using shorther/longer springs.
Mr.Crankyface so no car body?
Not sure what kind of car body would suit this chassis, if you have any ideas I'll take a look at it.
Mr.Crankyface a Hummer H2 or H3
Or some type of trophy truck
Шишига?
'
the transmission is more harder running while both shafts to both axles are bends...
not good design...
never know should be break...
watch this video...

Not a problem in this case since the yoke angles cancel out and the angle is not extreme.
