I am an avid O scale model railroader building my one rolling stock, scenery, and layouts.  I am using the Gridfinity system to organize my tools.  This is the first project that I created using Onshape CAD free maker version.  It is to organize my set os picks that I purchased from Micro Mark.  I hope that it is helpful to you however you use it.  The free version of Onshape requires that any models created with it along with any derivatives be used for nun-commercial purposes.  Please comply with that requirment and not ruin Onshape's licensing requirement.
