Yet another parametric box. Nothing special here. It's the right depth and height to be set side-by-side on my shelf. 240mm deep. 200mm high. 100mm wide. 3mm wall thickness, adjustable in the openscad file.

The OpenSCAD file is attached, but doesn't appear downloadable. It's short enough that I'll just reproduce it here:

BOX_WIDTH = 100; BOX_HEIGHT = 200; BOX_DEPTH = 240; WALL_THICKNESS = 1.5; union() { // Back: translate([0, -BOX_DEPTH/2 + WALL_THICKNESS/2, 0]) cube([BOX_WIDTH, WALL_THICKNESS, BOX_HEIGHT], center=true); // Front: difference() { translate([0, BOX_DEPTH/2 - WALL_THICKNESS/2, 0]) cube([BOX_WIDTH, WALL_THICKNESS, BOX_HEIGHT], center=true); translate([0, BOX_DEPTH/2 - WALL_THICKNESS/2, 60]) cube([80, 80, 20], center=true); } // Left: translate([-BOX_WIDTH/2 + WALL_THICKNESS/2, 0, 0]) cube([WALL_THICKNESS, BOX_DEPTH, BOX_HEIGHT], center=true); // Right: translate([BOX_WIDTH/2 - WALL_THICKNESS/2, 0, 0]) cube([WALL_THICKNESS, BOX_DEPTH, BOX_HEIGHT], center=true); // Bottom: translate([0, 0, -BOX_HEIGHT/2 + WALL_THICKNESS/2]) cube([BOX_WIDTH, BOX_DEPTH, WALL_THICKNESS], center=true); }
