RallyGrip — Custom Racing Shifter Knob for Thrustmaster TH8S

RallyGrip brings a rally-inspired look to the Thrustmaster TH8S with a sculpted handle, textured sides, and a rounded palm cap. The design combines three finger grooves with diamond-pattern grip panels. Smooth areas around the textured panels give the handle a clean finish, while recessed THRUSTMASTER lettering completes the racing theme. Features: - Sculpted finger grooves for a defined hand position.

- Diamond-textured side panels for added surface texture.

- Rounded palm cap and smooth rear surface.

- Integrated mounting socket.

- Approximately 110 mm tall × 42 mm wide × 35.4 mm deep.

The 3MF download includes the RallyGrip handle, supplied adapter, and a separate mounting test core. Import at 100% scale to preserve the socket dimensions. Printer and material settings must be selected in your slicer. Print the mounting test core first to check engagement before printing the full handle. This is an AI-assisted prototype. Digital mesh checks and sampled adapter-clearance checks have been completed, but physical fit, comfort, and durability have not been tested. The mounting socket retains geometry from the supplied th8s_knob_ice_cream_cone.stl. Preview images are digital renders.
