Description

Where to even start on this project... This is the continuation of the 3D Printed Rc Truck V3.
I remade 80% of the drivetrain and it's now a full-time 6x6 rock crawler.

The whole idea is to make everything easily replaceable if it breaks and all the hardware you need is screws and bearings.
Axles, "differentials", transfercase, driveshafts, wheels, chassis and so on is all 3D printed.

I have done all my prints in PLA with ~50% infill and 4 perimeters. Holds up well.
The axle shells could benefit from being printed in a more durable plastic, maybe copolyester.

Parts that need to be printed several of:
3x TruckV4AxleDiffGear1
4x TruckV4AxleDiffGear2
4x TruckV4AxleDiffHalfshaft
2x TruckV4AxleDiffHalfshaftFront
6x Truck
V4Ujoint(Connects to driveshafts)
2x Truck
V4Ujoint2(Outer steering joint for front axle)
3x Truck
V4CenterdiffUjoint
10x TruckV4UjointshaftUjointCross(Spider that connects the Ujoint brackets)
4x TruckV4UjointshaftA1(1 for each driveshaft)
3x Truck
V4FrameShockmount1
3x TruckV4FrameShockmount2
*2x Truck
V4FrameD4(ACC)(if you're printing the other Dx parts)
2x TruckV4RimFront
4x Truck
V4RimRear
**10x TruckV4TyreTreadedSolid

*TruckV4Frame_Dx(ACC) is an optional tray for counterweight/tech storage, requires a large printer or splitting

**TruckV4TyreTreadedSolid is ment to be printed in Ninjaflex or similar soft material.
Recommendation is to modify infill extrusion width to for example 50% which makes it underextrude on the infill, making a soft and mushy tyre that's nice to drive with.
Can also be replaced with Tamiya truck tires like these: https://goo.gl/gqUhKS
