I already have the full electronics worked out for a rechargeable, time-based smart-key system; now I need the mechanical side brought to life and documented so a machining house can move straight into mass production. Scope You will create production-ready mechanical designs (STP files plus manufacturing drawings, BOM and assembly notes) for three linked units: • the rechargeable smart key, • the battery-free lock drum, • and the desktop programming / charging dock. Key requirements – Multilayer construction that combines stainless steel, aluminum and titanium exactly where each metal’s strength-to-weight or corrosion advantage is needed. – For the key: an ergonomic grip, compact profile and proven durability against daily wear. – For the lock drum: robust tamper and pick resistance together with my electronics-controlled, automatic timed-relock mechanism. – All parts and tolerances suitable for CNC machining, investment casting or metal injection moulding at volume. – Clear call-outs for seals, fasteners, surface treatments and any custom springs or pins that interact with the electronics I provide. Acceptance I’ll consider the job complete when I receive: 1. Native and neutral STP files for every individual component and top-level assembly. 2. Fully dimensioned 2-D drawings with GD&T, finishing specs and exploded views. 3. A concise build manual that lets a factory set tool paths and QC checks without further input. If you’re confident with precision metal product design and have taken hardware from CAD to the production line before, let’s talk timing and hand-off details.
