In our team, we have created an unusual carrier for an annual report. Our aim was to design packaging for a flash drive, which creatively connects railway theme and in the same time serve as a very original packaging. This packaging should not be the only beautiful concept but at the same time fully functional and feasible product for small batch production. After several concepts and iterations we came up with the solution – we have used functional part, a metal rail which is placed into the 3D printed body that reminds of coal brick. The coal is connected with railway from ancient times and so we thought that this connection is easy to recognise and very original. Rail serves also as a guiding part for the shift of the packaging. And as a decor for the flash drive, we have generated the pattern from the visual of the railway network.
