Description du poste
I run a CNC machine shop in Ontario, Canada, and I’m launching a small consumer product: a machined metal “skeleton” case for BMW’s current key fob (the 2023+ key on the X3, X5, X1 and 5 Series). The concept is set. I need someone to turn it into clean, machinable CAD.
The concept
• Two metal cages, top and bottom, that follow the key’s tapered, curved shape. Not a rectangular block.
• A window over each button, so you press the key’s own buttons through the metal.
• Open sides between the cages, so the key’s chrome band and stripes still show.
• The cages are joined by small polymer posts and screws. The metal can’t form a closed loop around the key (radio signal), and I’ll give you those rules.
What I provide
• A reference model of the real key, from our measurements.
• Sketches and a rough 3D mock-up of the concept.
• Our machining limits: 3-axis mill, 2 operations per part in soft jaws, minimum inside corner radius and wall thickness.
What you deliver
• A parametric model of both cages, the posts and the screws, built around the key model with set clearance.
• STEP files plus your native Fusion 360 or SolidWorks file, with a clean feature tree I can edit.
• One revision after our 3D-printed fit tests, and one more after the first machined part.
You
• Strong at surface modelling of curved consumer products (not just extrudes).
• You understand CNC milling limits: tool radii, wall thickness, setups.
• 2–3 examples of curved parts you’ve modelled that were actually manufactured.
• Bonus: you’re into cars, or you’re near the GTA and can visit the shop.
Budget: CA$35–55/h depending on experience, estimated 15–25 hours (about CA$600–1,200 total). A fixed quote is fine too. Paid by milestone: first model, after fit tests, final files.
Timeline: first model within about 2 weeks of receiving the key reference model.
Terms: a short NDA before I share the mock-up, and the CAD files are assigned to the brand in writing.
