Will work with Truck V1 and Truck V2
Simple gearbox with helical gears for 540 brushed motors.
Print and add some grease, works great!
The hardware you need:
4mm bearings, I used 624zz bearings.
M3 grubscrews for locking the gears
You can see more videos of the V1 and V2 truck over at my youtube channel:
Edit 2016-03-12: Added bighelical32t_0.7m_PIN.stl, this is the output gear with a 1.5mm hole for putting a pin through the gearshaft, this seems to work better than just using grub screws but requires drilling through the metal shaft.
Edit 2016-03-27: Updated with new gearbox housing that'll work in both Truck V1 and Truck V2.
Edit 2016-04-23: Apparently the new gearbox housing had some tight tolerances around the gear so I made some more space there, only file changed is mount2.stl
Also added spacer.stl which helps align the gears, put it behind the big middle gear.
