Ferrari 458 Balloon Car

thingiverse

Bigger air pipes than before were needed, so the balloon attachment was enlarged and no longer too small, allowing the car to speed up due to larger exhaust holes.\r\nMy son's mishap of breaking the printed axles forced me to switch to DIN 912 M4 screws with a non-threaded section below the head, which led to the creation of new wheels that glide smoothly on them.
