Whole payload assembly
The rectangular prism frame is the CubeSat frame. Two of its sides are slightly longer than the other two (which was employed to ensure the L brackets could connect the sides as intended). There is a square top frame and a square bottom frame that attaches to the four CubeSat sides by L brackets. On top of either side of the CubeSat, bulkheads are attached (which allow the payload to be secured to the mission package tube of the rocket). Inside the CubeSat is the pressure vessel (bottom), with the battery holders and circuit boards sitting above the vessel. Within the vessel, the eyeball holder is secured to the bottom pressure vessel lid.
Pressure vessel (left) and pressure vessel lid (right)
The pressure vessel is by enclosed by a pressure vessel lid secured on both the top and bottom. O-rings were used to better ensure that the vessel was pressure sealed (the grove depicted in the pressure vessel lid is where the O-ring would go).
Eyeball holder assembly + bottom pressure vessel lid
The singular vertical piece mounted on the outer edge of the pressure vessel lid is the camera mount. Three cameras (one per eyeball), attach to the holes on the back of the camera mount. The three pieces which horizontal attach to the camera mount are the eyeball holder ribcages. Each are meant to have an eyeball placed on top, and the hole in the ribcage was intended for the optical nerve of the eyeball to sit inside (in order to provide extra security for the eyeballs). Lastly, the four pieces witch attach to the pressure vessel and each of these ribcages are the eyeball holder spines. When assembled with the rest of the eyeball holder parts, the spines mimic a spherical shape to provide a space for the eyeballs to sit inside (the curvature intended to provide a control for unintended eyeball deformation).
Battery holder/circuit board assembly
The flat components represent the Raspberry Pi circuit boards, while the boxes are an estimate of the battery holders and batteries. The assembly as a whole was used to get a crude estimate of how much volume these parts would occupy within the payload.
