v twin co2 engine

thingiverse

Very small CO2 engine by David Kerzel - an American design with imperial dimensions that were slightly tweaked to prevent collisions during assembly. The main modifications required are likely related to the con rod thickness, which may need to be strengthened with a spigot around the holes. All measurements were taken directly from the original drawings. This tiny CO2 engine will soon take shape as I print it out and attempt to assemble a demo model.
