This is a fully 3D Printed, ejection recovery system for 74mm model rocket fuselages.
It consist of two parts, a tube (fuselage) adapter that connects the lower section to the top and also serves as the cap that will hold the shock coord or string that connects to the piston.
The piston slides freely inside the upper fuselage (the part that holds the nose cone), and connects the shock coord to the lower section, nose cone and parachute.
The design is based on Joe Bernard's piston system
