Designed Gear Shift Knob

This is a 3D printable gear shift knob designed for manual transmissions with a lift-up reverse mechanism.
Model was specifically created for the Renault Clio II Phase 1.

The knob is intended to be press-fitted onto a smooth shift rod.

The inner bore is optimized for a press-fit on a shaft with a diameter of approximately 12–12.5 mm.

Compatibility notes:

• For slightly smaller shafts, the fit can be easily adjusted by wrapping the shift rod with electrical tape or heat-shrink tubing.

• For larger shaft diameters, the model can be modified directly in your slicer by adding a negative cylinder with the desired diameter to match your specific application.

This design allows for easy customization without the need to edit the original CAD file, making it suitable for a wide range of vehicles and DIY setups.
