GhostSpool

GhostSpool Since my child always enjoys rolling empty spools like wheels, I built this car based on CyberBrick. It perfectly mimics a Bambu reusable spool and can even be stored in an AMS. Design & Control Two actual spool faces act as wheels, driven by internal geared motors. Gravity ensures the central axis always self-centers. It is controlled via my previously built ModBrick (👈👈👈The model link and BOM are both available at this link.) configured as follows: [LS] - [JS] - [X] : [L2] [LS] - [JS] - [Y] : [L3] [RS] - [JS] - [X] : [R2] [RS] - [JS] - [Y] : [R3] [LT] - [TR] - [S] : [L1] [RT] -[TR] - [S] : [R1] [LB] - [NA] [RB] - [NA] The left and right joysticks independently control the speed of their corresponding wheels for movement and steering. The LT trigger handles pivot rotation, and the RT trigger controls forward/backward. This gravity-centric design results in significant inertia, making precise starts, stops, and straight-line driving a skill that requires practice—which is
