A miniature robot vacuum that glides on marbles. Size it for 14–22 mm marbles, add an engraved name and assemble a shell, spinning brush and LiDAR-style turret. Requires four marbles and either six 6 × 2 mm magnets with glue or three M3 screws.
Body diameter in millimetres. Height, caster spacing, and deck details scale with it.
Diameter of the marbles you will use, measured with calipers if you can. Every socket, retainer, and the turret seat are cut to this size, so the marbles roll freely without rattling. 16 mm is the standard player marble; 14 mm suits small ones and 20-22 mm the big shooters. Measure before printing — marbles vary.
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 sunk into a cone seat so only its glass crown shows, 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.
