The original mounting bracket for the bottle cars (black) was a bit unstable down the track due to the short length. The new mounting bracket (white) is much more stable down the line due to its longer length.

See videos for quick exchange of race cars and full race video of original vs final version. We will be printing over 100 bases of various colors with various colors of wheels as well.

The original racer

The Boca Bearings final version racer. 3D printed chassis, mounting bracket (wrapped in electric tape for better fitment), 3D printed wheels, 32mm O-rings for tires. Runs very straight however due to the increase in mass, it does not complete the full run as fast.
