  • ⚙Disclaimer: 
    This is a modification of the original files from 3Dsets. You will need to purchase the original files in order to build this mod in its entirety. Some crucial parts for the differentials are missing!
    I’ve included only the files I modified to make this build work.
     
  • 💡 Idea: 
    I really liked the model from @mbe075, but I was bothered by the lack of compatibility with an open differential. To me, it didn’t make much sense to build an even longer vehicle with straight axles - that would put too much stress on the drivetrain.
    So I put in the effort to build this mod. It took several ideas and iterations to get it working the way I expected.
     
  • 🛠 Build:
    The build process is quite straightforward. You can assemble the entire drivetrain using the manual provided by 3Dsets. The rest of the chassis and bodywork assembly is covered in @mbe075’s manual. 
    The only fiddly (and honestly, very annoying) part is the final assembly of the mid differential itself.
    Make sure to use the shortened pinion gear, driveshaft, and driveshaft cardan between the two differentials. I had to shorten them significantly and remove some of the fillets to:
    a) create enough clearance so the cardan shaft doesn't fall apart, and
    b) reduce the shaft angle so it doesn’t bind.
    You’ll also need to replace the original “Control Arm Rear – Upper.”
    Some parts need to be printed twice - these are marked with “x2.”
  1. Gather all the parts needed for the mid differential. The first half can be assembled just like in the original manual.You’ll need 3 pcs M3x12 cylinder head screws to close the differential.
    Make sure the second axle is already in place, with the axle gear screwed on.
    This part is pretty straightforward.
  2. You will need 3pcs M3x12 cylinder head screws to close the differantial. 
    Make sure the second axis is already in place with the screwed on axis gear.
    This procedure is straight forwared. 
  3. Now to the most annoying step of this subassembly: 
    I highly recommend screwing the drive gear onto Cage B before this step - the pre-cut threads makes the job a lot easier! Screw the drive gear onto the top of the cage.
    You’ll need an angled hex key for this fiddly step. (trust me, I tried everything and couldn’t find a more satisfying solution)
  4. The rest of the subassembly is a piece of cake - and you’ll end up with something that looks like this:

     
  5. Enjoy the rest of the build. 
  6. Don’t forget to post a “Make” once your build is done 😉

Cheers!
