Parametric Vase-Mode Storage Box

This makes a rounded cubic box of a given width/depth (same value) and height. The roundness of the corners is adjustable according to your preference. There is also provision for a one-line label centered on one face, debossed into the surface. (This has been a bit troublesome to produce, at least on smaller boxes. I'm printing a plain 150x150x180mm box as I write this; perhaps a label would've worked better here.)

Adjust the width, height, and roundness parameters at the top of the OpenSCAD file. For the label, set the label, label_size, and label_depth parameters as appropriate. (label_depth should be kept to something less than your printer's nozzle width.)

Uncomment either body() or lid() at the top, and render to STL. Print in spiral-vase mode with three bottom layers.

STLs for a 50x50x50mm box are included as an example.

This needs a fairly recent build of OpenSCAD to render. I had been using a build for 64-bit Windows from 6 January 2018, but was getting asse
