This is a desktop model or a visual learning model, purely for studying or a cool fidget toy

Inspiration + Explanation:

I made this project to help schools, help other people with a mechanical passion and made this for the love of mechanical engineering

Since this model has a lot of parts, here is the instruction below. It is going to be long and slightly confusing so read it twice or more:

The parts list an quantity you need to print :

friction disc x6

plastic disc x6

retainer 18mm x2

retainer 20mm x4

shaft x2

side gears x2

spider gears x2

spring x2

spring pad x2

wheels x2

cage x1

pinion gears x1

spider gears axle x1

stand x1

Lets start with the main assembly
+ First take your cage module
+ assemble the side gears first. Start by taking the side gears, add the shaft into the smaller gear pocket After that put on the friction discs and the plastic discs in the following order: Friction > Plastic > Friction >                                                                                                                                          Plastic> Friction> Plastic

Do the same for the other side gears
+ Next slot the side gears onto the side of the cage (Left and Right), make sure that the tab of the plastic discs (the pop out thingy) slot into the rectangle pocket on the cage. Only do one first

Next, the stand:
+ First take your assembly from last step and. Next put on the 20mm retainer on the first shaft almost all the way in (not fully in), after that slot the shaft into one of the hole on the shaft (Make sure the ring gears is on the left side of your hands), then slot in the second 20mm retainer not fully in but around 1mm away from the wall
+ After that put in your other side gears conjunction into the cage exactly like the first one, this time only one retainer outside
+ Next, take your spider gears and the axle for it (spidergearsaxle), put one gears on one side and the other gears on the other side, after that slot the spider gears into the small circular slots. You might need to do some bending to get them in
+ Finally, take your pinion gears, slide in the 18mm retainer (not fully in) then put it through the angled hole and finally put in the last 18mm retainer (make sure its 1mm away from the wall). Forgot to mention that after doing all of that you can slide in the wheels at the end of the shaft for some weight and increase momentum

Last one, the springs:
+ First take your two spring pads, then put only one of two springs first. After that, wedge them in between inside the cage, finally put on the final spring for them to push the side gears out

What each part does:
- The cage: House every components
- The spider gears: To let two side gears turn at different speed
- The side gears: Connected with the shaft and transfer the power to the wheel
- The spring and spring pad: To push the side gears outward to apply friction on the plastic discs and friction discs to transfer power
- Ring gear and pinion gear: To transfer the power to the main differential
- Clutch pack (friction discs and plastic discs): The main mechanism for the LSD, one side is going to break free if it has more torque than the other side, preventing random slip
- Spider gears axle: To hold them together
