Airy shift knob

ErgoShift – Custom shifter knob for the Thrustmaster TH8S

3D-printable knobs for the Thrustmaster TH8S Shifter, ‘Shift your way’.

An accessory that not only looks great and takes the visual appeal of your sim racing setup to a whole new level, but above all improves the ergonomics and overall feel of every gear change.

Key design features:

• Perfect compatibility: The model is precisely dimensioned for use with the official Thrustmaster TH8S adapter. Simply print it, fit it, and you’re ready to race.

• Ergonomics and grip: Anatomically shaped for your fingers / Textured surface for a more secure, non-slip grip / Stylish design.

• Easy 3D printing: The design is optimised for standard FDM printers. No supports required! And anyone can print it.

• High stability: Fits securely onto the adapter, so it doesn’t twist during sharp gear changes.

Recommended print settings + filament:

• Material: PETG or PLA (I recommend PETG for greater durability during prolonged use

• Layer height: 0.10 mm – 0.20 mm (ideally 0.15 mm or less for a smooth, comfortable surface).

• Infill: 20–30% (I recommend Gyroid for good weight distribution and strength).

• Perimeters: 3–4 for maximum thread strength and internal stability

Please note: Designed for the Thrustmaster TH8S gear stick. This is a third-party accessory and not an official Thrustmaster product. Fitting tolerances may vary depending on printer calibration, material and print settings; this part CANNOT BE SCALED.
