Helios Mk-III
Our STEM Racing car: a CO2-powered Formula prototype, designed in CAD and 3D-printed by the team. Small enough to hold, obsessive enough to keep us up at night.

One car, still on the bench
Right now we only have our Formula prototype. We're testing it and refining the design before we commit to a final race car.
The brief is simple and brutal: fastest car down the track wins. So we chase the tenths everywhere: a slimmer body, lighter wheels, a cleaner line off the tether. Every print teaches us something, and every version gets a little quicker than the last.
