D3Prototypes

Builder-Led Prototyping Studio

From hardware idea
to working device.

D3Prototypes helps founders and teams turn hardware ideas into working devices — fast enough to test, clear enough to show, and real enough to move forward.

We help bridge the gap between “this should exist” and “here it is, working in front of you.”

If you can describe the product, we can help make it real.

Built from the bench, not a boardroom.

D3Prototypes workshop in Toronto — design desk, 3D printer, and electronics bench for in-house hardware development.

D3Prototypes is a Toronto-based, builder-led hardware studio serving founders and product teams across North America.

Our work is practical by nature. We design, build, test, and revise quickly, using each prototype to answer real engineering questions and move the product closer to a version that can be manufactured.

As the design matures, we help connect the work to capable partners for PCBs, enclosures, sourcing, kitting, and assembly.

Product offerings

Named product lines we build with you — same custom process as the rest of the studio. Sit down, design it, then we ship finished units or hand over the files.

NFC business cards people keep

A printed card gets tossed. A useful one stays in a pocket, on a keychain or on the workbench.

We build NFC identity into objects people can keep using — a working tool, a hardware token or a branded piece of kit. That might be a ruler-and-caliper card, a desk object or something designed specifically around what your business does.

We’ll work with you to invent it, develop the design and build the prototypes. Then we can produce the finished units or hand over production-ready files.

Telematics · Fleet Operations

Commercial fleet material-tracking system

Work on a publicly deployed winter-maintenance platform: in-cab operator hardware, custom wiring harnesses, and rugged spreader-side sensing to track material use in the field. Contributions also included integration support for GPS-linked reporting and operator-facing guidance in demanding commercial operating conditions.

Health-Tech · Smart Home

Smart in-home medication companion prototype

Work on a connected prototype for a smart in-home medication companion — from early mechanical concept through integrated system bring-up. Scope included enclosure and mechanical iteration, embedded control and motor/sensor integration, vision and detection logic, audio and network behavior, and PCB/BOM coordination toward small-batch prototype manufacturing — with ongoing refinement toward pilot-ready units.
