Modular Cat Tower CAD Engineering

My full-scale cardboard mock-up of a 6–7 ft cat tower has proven the concept; now it needs to become a rock-solid plywood product that ships flat, goes together IKEA-style, and stays absolutely steady under several energetic cats.

You will start from my photos, dimensions, and notes and build a parametric 3-D CAD model, specifying high-grade plywood panels and a fastening scheme built around threaded inserts, furniture bolts, cross-dowels, and concealed steel brackets. All exterior faces remain in a natural wood finish, so hardware must sit flush or hidden.

Structural robustness is non-negotiable. Please size every panel, joint, and base element so the centre of gravity stays low and dynamic jump loads are covered with a comfortable safety factor. Provide stress and stability validation—hand calculations or FEA are fine as long as the assumptions are clear.

Deliverables
• Native CAD files (SolidWorks, Fusion 360, or similar) plus STEP/IGES
• Fabrication drawings with tolerances, cut lists, and CNC nesting layouts
• Complete BOM with hardware call-outs
• Consumer-friendly assembly guide with step-by-step visuals
• Short structural report summarising load cases, stress plots, and tipping analysis

The cardboard prototype locks the overall geometry, but I welcome smart tweaks that increase strength, reduce weight, or simplify assembly while staying true to the modular idea. Once onboard I’ll share all reference material; let me know your toolchain and an estimated schedule for the first design review.
