Asked GPT-5.5 and Opus 4.8 to replicate this robot in ForgeCAD. While further iterations can get closer, I find is surprising how different these models are.
First Opus, second and third the GPT model.
stop playing with these other batteries, just spec a JoyCon battery for your hobby project. You can buy them on Amazon ALWAYS. The pinout is the same ALWAYS. The connector is small! Just do it! Stop buying random shit off of Amazon!!!
