Rally Grip – Ergonomic Thrustmaster TH8S Shifter Knob
Give your sim racing setup a new feel with Rally Hex, a futuristic, faceted shifter knob designed for comfortable grip, easy assembly, and creative customization.
Inspired by rally car controls, its symmetrical hexagonal shape combines a distinctive look with a tactile surface designed to feel good in your hand.
🏁 Designed for comfort and control
The ergonomic shape and fine surface detailing give your hand a comfortable, secure-feeling grip while shifting. The faceted silhouette gives Rally Grip a distinctive motorsport-inspired look without sacrificing practicality.
🎨 Multicolor look, without a multicolor printer
Create your own color combinations using separately printed parts. No MMU, AMS, or other multicolor printing system is required — just print the parts in your chosen filaments and assemble them.
Want an even better tactile feel? Print the optional grip ribs in TPU for a softer, more comfortable contact surface.
🔩 Simple assembly — no glue, no extra hardware
No glue required.
No need to buy additional screws or other hardware.
A single 3D-printed screw holds the assembly together.
Assembly requires only a standard flathead screwdriver.
Print the parts, assemble them, tighten the printed screw, and you're ready to race.🛠 Designed for the official TH8S adapter
The knob is designed to work with the official Thrustmaster TH8S adapter:

Print the adapter separately if you don't already have one. Please follow the adapter project's instructions for mounting it to your shifter.
🖨 Recommended print settings
Layer height: 0.2 mm for the main parts.
Fine detail: 0.1 mm is recommended for the upper part of the top component if you want a finer finish.
Grip ribs: Use TPU for a softer feel; a firmer filament can be used for a rigid version.
Multicolor: Print the individual parts in different filament colors and assemble them.
Assembly: Use the included 3D-printed screw. No glue or additional hardware is needed.
Note: Depending on tolerances of your setup middle part can be scaled up or down (along Z axis only!) to fit ribs.
Make it yours
Choose your favorite colors, experiment with TPU grip ribs, and build a shifter knob that matches your racing setup.
