This is open modular electronic rack. You can use it to build any rack configuration with your specific needs. In the attached example, I put three shelves to host all my electronic needs for CNC plotter. The first holds all power circuits and switches, the second holds raspberry pi and the third holds arduino uno with CNC shield. You can use the attached scad files to customize your model. You will need to include “m_rack.scad” which holds the base code. You can check “pi4_shelf.scad” for example.
For the project you will need 4 rack leg (check "rack_leg".scad" to configure shelves spacing). To attach shelf to leg, you will need four m3 6mm screw and four m3 nuts. You can use rack_jig to help with the build.
