Voronoi-mesh CanSat chassis featuring a centered 6-cell battery holder and a bottom-mounted Arducam slot.

This setup balances structural integrity, weight optimization, and a low center of gravity.

3D CAD (Computer-Aided Design) is essential in a CanSat project because it allows teams to precisely fit all electronic components, sensors, and recovery systems into a strict soda-can volume before physical assembly

Material used by me: Nylon 12

3D Structural Overview

Outer Frame -Parametric Voronoi lattice mesh cylinder.Minimizes drag, reduces overall weight, and maintains impact strength.

Core (Center) - Concentric 6-cell vertical battery array (e.g., 18650 or AAA).Concentrates mass along the central axis to prevent rotational wobble during descent.

Base (Underneath) - Integrated Arducam camera slot with downward lens exposure.Protects camera PCB while providing clear nadir ground imaging.

3D Printing Recommendations

Material: Use PETG or Carbon Fiber PLA (PLA-CF). Standard PLA is too brittle and may shatter upon ground collision due to the hollow pockets of the Voronoi pattern.

Orientation: Print the frame vertically (base-side down). This ensures the Arducam slot layer prints cleanly on the bed and minimizes the need for internal overhang support structures inside the Voronoi geometry.

Simulation result- (FEA) Very Strong
