01 / Find your hardware
Shop by device.
Start with the hardware in your hands. Each collection brings together accessories engineered around that specific device.
02 / From first principles
The hardware comes first.
Every ProtoSolo product begins with the hardware itself—not someone else’s accessory. We measure, scan, model, prototype, test and refine each design around the device it was created for.
The CAD model is a starting point. Physical prototypes and real-device use reveal what the screen cannot.
01
Measure
Understand the real device, its interfaces and the problem to solve.
02
Model
Develop original geometry around the hardware and intended use.
03
Prototype
Move quickly from digital form to a physical assembly.
04
Test & refine
Evaluate on the actual device, learn and iterate.
03 / Engineered to stay in service
Assemblies, not disposable objects.
“We design products as assemblies, not disposable objects. When practical, individual replacement components are available so an unfortunate drop doesn't have to mean replacing the entire product.”
04 / Custom projects
You bring the idea.
We’ll bring the engineering and fabrication experience.
You don’t need CAD experience, measurements, technical drawings or a ready-to-print file. You don’t even need to know exactly how your idea should work.
Tell us what you want to accomplish. We’ll work through the problem together—develop the design, prototype it, test it, refine it and turn your idea into something real.
Something designed specifically for your needs.
