Box extrude extension

Thanks, I changed bottom_thickness_delta to bottom_thickness, default to shell_thickness.

That's indeed even better. What's the purpose of the following code: intersection() { linear_extrude(btm_thickness) square(65536, center = true); // 65536: just large enough size to cover the children

    linear_extrude(height, convexity = convexity, twist = twist, slices

= slices, scale = scale) children(); }

Isn't it simpler to just use: linear_extrude(btm_thickness, convexity = convexity, twist = twist, slices = slices, scale = scale) children();

Not that simple. Given the code:

use <box_extrude.scad>;

box_extrude(height = 30, shell_thickness = 2, scale = 1.5) 
    text("X", size = 40, font = "Cooper Black", valign="center", halign="center");

Your simpler code will generate a bottom like this:

Although some math might be useful for creating a seamless bottom, the intersection section is an easy way, especially for situations that users specify twist, slices, and scale.

Indeed, for those use cases, something like this is needed and still simple. Thanks for explaining.
