Hermes 2 Lower Electronics contains three 3D-printed enclosures, one for each of the two cameras, and one for the DAQ.
Camera Enclosures
The camera enclosures are printed from PLA plastic. The curved section is mounted to the inside of the retention ring using the two upper holes, and its shape allows it to fit snugly against the side. The two vertical holes on the bottom match holes on the switchband, allowing access to the camera's controls from the outside of the rocket so it can be turned on prior to launch. The two holes on the top face of the enclosure allow attachment of the recovery guard. The camera sits inside the rectangular compartment, its lens facing upwards. Inside the compartment, the plastic is ribbed to keep the camera more insulated, due to the risk of a hot retention ring during launch.
DAQ Enclosure
The DAQ enclosure has a similar design to the camera enclosure. The main difference is that it is split into two parts, a body piece (left) and a mount for the DAQ (right). The DAQ is screwed into the mount, which allows it to be held securely, and the mount slides into the body piece. The body piece also includes an additional hole on the bottom, where wires that connect the DAQ to other sensors can pass through.
