If a product belongs in your vehicle, it should look and fit like it was designed there from the beginning. Precision hardware, built to your car's actual geometry — not adapted from a universal part.
Three designs in development for Tesla Model 3 and Model Y: concept stage, revision-controlled from day one. Every stage is shown honestly: nothing is called validated until a documented fit check exists. Tell us which one you're waiting for.
One vehicle-specific screen interface; swappable modules for detectors, MagSafe, phone and camera.
Soft-contact gap protection and storage shaped to the Model 3/Y cabin — no rattles, full seat travel.
Purpose-built exterior handle geometry for easier access and all-weather use — mechanical attachment first.
Most automotive accessories are built for the broadest possible range of vehicles. That usually means compromises — generic mounting hardware, awkward fitment, unnecessary adhesives, rattles, blocked controls, and products that look added on rather than integrated.
We take the opposite approach. FitGrid Lab develops precision-fit accessories around the actual geometry of each vehicle and the equipment they are designed to support.
Generic geometry, adhesive or friction, gaps everywhere. It works, until it slides, rattles, or peels off in August.
Built to the cavity's real dimensions. Locates on the vehicle's own features, installs cleanly, removes cleanly, and disappears into the interior.
Every FitGrid design targets one platform's actual geometry, stated per generation. Nothing is marked verified until a documented fit check on a real vehicle exists.

Drive something else? Request a fitment — requests steer what we engineer next.
We believe automotive accessories should work together. FitGrid Lab is developing modular mounting systems where one carefully engineered vehicle interface supports multiple accessories.
Every FitGrid design moves through the same staged discipline, concept to available, revision-controlled at each step. The full seven-question interface process lives on its own sheet.
Capture the actual vehicle interface — surfaces, features, tolerances.
Design around contact, motion, tolerance, install — reversible by default.
Fit checks, cabin-heat exposure and road testing will be run and documented per SKU — results published, never assumed.
Revision-controlled hardware with documented compatibility.
Tell us your vehicle and the accessory that never quite fit. Requests are aggregated by vehicle × problem and directly steer the FitGrid development queue.
First designs are in development now. Tell us what you drive and we'll write when there's hardware worth your time — launch notice, new fitments, revision notes.
