A robot vacuum toy that really glides — on standard 15-17 mm marbles. Three marbles ride in ball-caster sockets under the chassis (front caster plus two drive-wheel positions, just like a real robovac) and a fourth rests in the LiDAR turret dish as the glass sensor dome. Flush AMS button inlays, an engraved deck name, a shadow-line front bumper, a spinning three-arm side brush, and a roller window underneath complete the look. Close the shell with three pairs of glued 6x2 mm disc magnets or three M3 screws. Prints support-free on three plates.
Body diameter in millimetres. Height, socket spacing, and deck details scale with it.
How the top shell fastens to the chassis: three pairs of glued 6x2 mm disc magnets (like the inspiration car), or three self-tapping M3 flat-head screws driven from below into printed pilot bosses.
The LiDAR turret sensor dome: a fourth marble resting in a driver-style dish, or a fully printed dome for builds with only three marbles.
Up to 10 characters engraved across the front deck. Leave empty for a blank deck.
