Parametric SMD Storage Cartridges (OpenSCAD)

There are lots of SMD storage solutions out there that promise customizability (including this one), but every one I've run across requires expensive (or at best, free-as-in-beer) proprietary software that would also amount to yet another package to have to learn how to use when all I want is to put some organization to the parts I've accumulated for various projects.  This one's different: it uses OpenSCAD to generate storage cartridges for whatever size of SMD tape you need, kn whatever capacity, and with options to hold multiple cartridges together with magnets and/or a DIN rail.  It borrows several ideas from similar gadgets I've seen elsewhere.

The source file is reasonably well-commented so that it should be easy to figure out what to tweak to produce the sizes you need/want.

I've also included a script to produce thin, quick-printing labels that you can glue on, since 8mm paper labels for label printers seem to be hard to come by. They're intended to be printed in two colors: the first two layers in the background color you want, then the last three in the text color you want.  

This project is also on GitLab.

din_rail.scad is from Printables.com and is included for reference. 

fontmetrics.scad is from Thingiverse and is used by the labeler script.
