I designed a larger shell for the Robak V2 car and reserved a small opening in it for installing my power switch. In addition, the shell is equipped with several screw holes, making it easy to firmly clamp and fix the shell. All you need to do is gently screw in a few M3 bolts
Other spare parts can be downloaded from the official website or obtained through video instructions:
