The hardest part of this build looks like the parametric engine behind it, and the maker seems to have handled it well. The cabinet was modelled in Fusion 360 from the ground up for CNC work, with formulas in the parameter table driving the sketch constraints and the joinery dimensions. Tenon length is worked out as half the mating part thickness minus a clearance tolerance, and dado depth comes in at half the host panel thickness. Getting all of that to recalculate cleanly for any size is real engineering, not just a scaled sketch.
The prototype carcass ran 18 inches deep, 20 inches wide and 32 inches high, with two large drawers low down and four shallow ones up top. A 3/4-inch sheet of birch cabinet-grade plywood formed the main structure, and a second 1/2-inch sheet supplied the base, back panel and drawer components. Cutting was done on an aluminum extrusion gantry router controlled from an Asus laptop, with a metal touch block and a ground wire and clip setting the Z-axis zero. A blue-coated 1/4-inch spiral down-cut bit milled the dados, slots and perimeter outlines, and a cordless impact driver secured the corners of the workpiece.
Several details stand out to me. Overall height adjusts automatically for user-specified caster heights and countertop thicknesses, and hole locations recalculate along with the dimensions. The hardware list includes 100lb soft-close drawer slides, 4-inch nickel pulls, removable lift casters with clamps, a second clamp set, and adjustable feet.
The one hiccup came from the 1/16-inch end mill used for shallow drawer slide pilot holes: the holes filled with paint during finishing and had to be cleared out with a punch tool and a screw. The maker now recommends a 1/8-inch diameter bit for future pilot holes. Doors, hardware, shelving and sliding shelf options are still being designed, and face frames, trim and custom doors for kitchen and bath use remain to be added, so there is plenty still open on this one.
