R2D2 Modular control unit (MCU)

The latest version of the documentation is also attached where the assembly is described and also a list of needed parts!General motivationThere 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 the brain.Special thanks to everyone who inspired me, particularly John van Ohrs with his R2D2 modular electronics panel by jfmvoers and Tim Eebel with his MarkIII Hinged Electronics Panel.RequirementsThe 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)!To allow access when installed, the entire unit must be hinged (no tools required for this step).The design must be modular, allowing it to be adapted to specific requirements.The design must be based on a grid (60x60mm) a
