Here is a parametric organizer designed with OpenJSCAD.
This is meant to be cut out on a laser cutter, although it does generate STL files.
You can customize and download your own organizer here.
This is still slightly a work in progress, although I have printed a few boxes that have turned out alright. You will need to adjust kerf within your CAD program, as I do not have it built into the script currently.
The UI on the generator is a bit clunky, looking for suggestions on how I might improve it.
