3D Printed Rc Truck V4
Files can now be found at Cults3D
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:
6x Truck_V4_Ujoint(Connects to driveshafts)
2x Truck_V4_Ujoint2(Outer steering joint for front axle)
10x Truck_V4_Ujointshaft_Ujoint_Cross(Spider that connects the Ujoint brackets)
4x Truck_V4_Ujointshaft_A1(1 for each driveshaft)
*2x Truck_V4_Frame_D4(ACC)(if you're printing the other Dx parts)
*Truck_V4_Frame_Dx(ACC) is an optional tray for counterweight/tech storage, requires a large printer or splitting
**Truck_V4_Tyre_Treaded_Solid 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
6x RC shocks(~80mm recommended)
18x 6700zz bearings
45x M3x8 grub screws
6x countersunk M3x16
26x rodends(hole in ball needs to be 3mm)
Threaded rod to fit the rodends(will depend on what you buy):
-suspension links are 64mm eye to eye
-panhard rod is 75mm eye to eye
12x Countersunk M3x16
9x M3 nuts
4x M4 nuts
4x 4mm rod, 80mm long(Frame reinforcements)
4x 6700zz bearings
3x Countersunk M3x16
1x Transmitter and receiver of your choice
1x Standard size servo(I used Futaba S3003
1x 12V 550RPM motor(I used this: https://goo.gl/axambY )
1x ESC to drive your motor(I used this: https://goo.gl/xMoZTQ)
