Real products. Engineered in this practice.
Some of these shipped before Primed.Design existed as a named practice. All of them share the engineering discipline we apply to Amazon sellers today.
Bamboo-lidded pill splitter
Industrial design and CAD for an injection-moulded body with a natural bamboo lid insert, engineered for clean splitting and assembly.
Amazon relevance: a moulded consumer device with a material-led point of difference, the exact move off a generic white-label SKU.

Cast pebble pendant
Surface-continuity engineering and CAD prepared for pressure casting, holding a clean reflective form across a hand-sized shell.
Amazon relevance: form and finish are the product. Getting surfaces right in CAD is what separates a premium listing from a copy.

Camera rear-frame bezel
Injection-moulding design and DFM for a precise enclosure component, where fit tolerance against existing hardware was the whole brief.
Amazon relevance: accessories that mate to known hardware live or die on tolerance, the difference between five-star fit and a returns problem.

Teardrop adventure trailer
Full-vehicle CAD across body and chassis, resolving panel geometry, door and window apertures into a buildable structure.
Amazon relevance: large multi-part assemblies prove the practice can hold a whole product together, not just a single part.
Airborne wind turbine concept
Concept engineering and patent-stage design for a modular ducted-rotor array, taking a novel idea into defensible geometry.
Amazon relevance: this is the IP-first thinking sellers need when the goal is owning something a factory cannot resell.
Relay module mount
Enclosure and mount design with a 3D-printed housing, sized around an off-the-shelf PCB for secure fit and serviceable access.
Amazon relevance: housing a bought-in component is the same problem as turning a generic insert into a branded, protected product.
Several of these projects weren’t built for Amazon, but the engineering problems they solved (DFM, IP, unit economics, supplier-managed tooling) are the same problems Amazon sellers hit when they move off white-label. We’ve re-framed them with that lens.
