This is a 9:1 ratio gearbox designed for Drommon's Wraith Clodbuster build.
It works perfectly with a Hobbywing 3700KV 3660 motor and a 3S LiPo battery. This setup uses a Traxxas Bandit TRX 9480 differential with 500K oil.
I tested a Traxxas Slash/Stampede 2380 differential and without a center differential, but with a 3S LiPo battery, the monster truck is difficult to control.
I've uploaded the .STEP file, so you can easily make the necessary changes.

The gears were printed using Bambu PA6CF.
The housing of the first print was made from Bambu ABS-GF, but after many high jumps over two months, it broke at the motor mount. Since switching to PA6CF, there has been no breakage so far.
