R2-D2 Modular Body Backpack General motivation There are many good solutions for organizing all the control electronics for the whole selection of R2D2 bodys. However, none of these solutions fully met my requirements, so I designed my own interpretation of a modular control unit. But so that I can also mount some components in the body, the Modular Body Backpack was created. Requirements The module must be completely removable as a single unit to allow work on it at the workbench. Everything must be possible without any special tools, i.e., plug-and-play instead of screws (almost achieved)! The design must be modular, allowing it to be adapted to specific requirements. The design must be based on a grid (60x60mm) and offers panels ranging from 1x1 to NxN. Images
