This is a chassis for Smartibot that has been designed to require a small amount of filament and print on 3D printers with small build volumes. It is ideal if you want to replace the cardboard parts of the A.I. bot with something more durable, but still use the bot with a Smartphone mounted in the same way as the cardboard version.
The largest part is 72 mm x 72 mm x 41 mm. The wheels take an 'O' ring with 45mm outside diameter and 3.5mm thickness.
0.8mm nozzle, 0.3mm layer height
