Customizable Thin Walled Boxes

Got stuff floating around in your drawers that needs to be tided up? Look no further.

OpenSCAD remake of Glaedi's IKEA ALEX Boxes, which are great, but difficult to customize and missing a few sizes I wanted. Every aspect of this design, including the corner radius and wall thickness, can be customized to make the best use of your space.

Sizing details:

The 1x1 box is 6cm square on the outside edge (minus a 0.5mm on every edge to account for some error in printing and ensure it's a loose fit). Other boxes are similar -- the 2x3 box, for instance, is 12cm x 18cm minus 0.5mm on all edges.

This is my first thing, so bear with me if I've done the Customizer settings wrong on the first pass.
