Prompt

from this soap dish, create another part which "contains" this dish (to collect water) - remove all the logic of the actual dish and create just its container (tolerance 1mm)

OpenSCAD Code

// Honeycomb Soap Dish - Drip Tray (Container)
// Designed to fit a 135mm x 135mm dish

// --- Parameters ---
dish_width = 135;
dish_height = 135;
dish_depth = 24;        
dish_corner_radius = 35;

tolerance = 1.0;         // 1mm gap on all sides
wall_thickness = 2.0;    // Thickness of the tray walls/bottom
tray_height = 8;        // Slightly shorter than dish for easy removal

$fn = 80;

// --- Calculations ---
inner_w = dish_width + (tolerance * 2);
inner_h = dish_height + (tolerance * 2);
inner_r = dish_corner_radius + tolerance;

outer_w = inner_w + (wall_thickness * 2);
outer_h = inner_h + (wall_thickness * 2);
outer_r = inner_r + wall_thickness;

// --- Main Render ---
difference() {
    // Outer Body
    rounded_square(outer_w, outer_h, tray_height, outer_r);
    
    // Interior Cavity (Hollowed out)
    // Shifted up by wall_thickness to leave a solid bottom
    translate([0, 0, wall_thickness])
        rounded_square(inner_w, inner_h, tray_height, inner_r);
}

// --- Modules ---

module rounded_square(w, h, z, r) {
    // Centers the object and creates the rounded rectangular prism
    translate([-w/2 + r, -h/2 + r, 0])
    hull() {
        cylinder(h=z, r=r);
        translate([w - 2*r, 0, 0]) cylinder(h=z, r=r);
        translate([0, h - 2*r, 0]) cylinder(h=z, r=r);
        translate([w - 2*r, h - 2*r, 0]) cylinder(h=z, r=r);
    }
}
