The chassis was inspired by the public-source CubeSat design: Universal 1U Cubesat by Juliano85 - Thingiverse and 3D printed with PLA. PLA was chosen over other potential materials such as PETG because PLA was stiff, durable, and lightweight. The thickness of the walls was 0.15' to optimize weight and durability while allowing the screws (particularly the eye bolts) to fully fit through the walls. The interior space of the design was 7.5x8x7' mostly because of the spectrometer and muon detector, whose dimensions were 6.3x4.3x3.5' and 2.7 x 2.25 x 37x2.25x3.3 in ' (when stacked on top of each other) respectively.
