Fully parametric box generating library for openSCAD. You can even use the new Thingiverse customizer to access high level generation properties or download the library base and build your own (and then cut it on a laser cutter versus print it!). Code is on github.
I would love to win a Replicator so if you would all be so kind as to go view it, download it, or check it out using the customizer app. Need eyeballs!
