CubeSat module

This model is designed according to the size of the Cubesat. It should be produced by the process of additive manufacturing with the material PEI polyetherimide. I did not choose the metallic materials made with laser sintering method because they cost is absolutely highest than ordinary sheet of aluminum cut and folded. To withstand extreme temperature changes of outer space would be better to cover the structure with vacuum metallizing chromium to reflect solar radiation and minimize the jump in temperature between the part exposed to the sun and one in shadow. I suppose that one of the problems encountered in the construction of a picosatellite like cubesat is the development of the devices. The electronic cards can be tried separately but sometimes included in the cube like a real puzzle are not easily accessible. I have therefore designed the cube so that it can easily be opened in two halves with few screws, circuit boards are inserted into the notches of internal part of rails. The basic model 1U has two halves perfectly symmetrical so is necessary only a single model to print. The dihedral thus obtained has a good dimensional stability. This configuration is allowed by the technology of 3D printing. A pair of feet is removable in order to insert the spring plunger whit proper locking nut. The sides of the cube are drawn with reinforcements and ribs adequate to withstand vibration that I suppose are high during the launch phase The connecting screws are common self-tapping screws for plastic, , so I drew the appropriate preparatory hole, while the holes that contain the spring plungers must be tapped. Clearly it is a basic module which can be modified according to the specific needs of each satellite that feature a wide variety of devices The weights of the individual modules are the following: ** PEI Specific gravity 1.27 1U gr 100 - screws and spring plunger gr. 5.45 1.5U gr 137 - screws and spring plunger gr. 7.18 2U gr 178 - screws and spring plunger gr.
