Tamiya tank chassis

This chassis is specifically designed to be paired with this battery pack https://www.thingiverse.com/thing:2346235 . By doing so, it achieves a low center of gravity, resulting in exceptional stability. The vertically mounted gearbox leaves ample space for electronics and future additions. To assemble the chassis, you will need 2 M3 X 10 bolts and 2 nuts. Note that the voltage output from the 6 AA batteries exceeds the motors' handling capacity, necessitating the use of PWM to prevent damage. I personally utilize a maximum duty cycle of 60%.
