Here's a look at the OpenSCAD code behind this project. // Define module parameters module housing(height = 10, width = 20, depth = 30) { // Calculate dimensions for the housing housing_width = width; housing_depth = depth; // Create the base of the housing translate([0, 0, height]) cube(housing_width, housing_depth); // Add the sides of the housing translate([-width/2, -depth/2, height]) linear_extrude(height) polygon(points=[[0,0], [housing_width,0], [housing_width, depth]]); translate([width/2, -depth/2, height]) linear_extrude(height) polygon(points=[[0,0], [-housing_width,0], [-housing_width, depth]]); // Add the top and bottom of the housing translate([-width/2, -depth/2, 0]) cube(housing_width, housing_depth); translate([width/2, -depth/2, 0]) cube(housing_width, housing_depth); }
