Hej! By the end of the week an important milestone will be reached: the production of the Metal Rings. In the last days we checked drawings and CAD files, thus only the final review is missing and than we can make the order!
The Metal Rings are very important for the structure of the FFUs (Free Falling Units) since all the other structural components and the two PCBs will be fixed to them.
The Rings will be produced by Mixtrum and will be made in Aluminium Alloy 6082. We decided to order the Rings, instead of producing them inside KTH for two reasons. First because their shape is pretty complex so a CNC machining tool is required. Second, since we have to screw together Internal Ring and External Ring, the tolerances must be very small!
Here you can find some CAD rendering of the rings!
