Done designing the gearbox V3A, I might do other ratios hence the A.
This is much sturdier than the V2 design and should work fine with the V3 truck, I've testdriven it quite roughly both on tarmac and indoors without issues.
You can check out the assembly video for this and the other parts over at my youtube

Hardware needed:
4x M3x16 for the housing cap
2x M3 for mounting the motor
2x M3x10 for the bearing cap
1x M3x16-25 for the U-joint attachment
2-3 M3x16 for mounting the gearbox to frame
1x M3 grubscrew for securing motor gear to shaft
4x 6700zz bearings(10x15x4mm)
