AEROLITH Ergonomic THRUSTMASTER TH8S Shifter Knob

AEROLITH — Custom Shifter Knob for Thrustmaster® TH8S

Sculpted for control. Designed for the drive.

Give your sim-racing setup a distinctive upgrade with AEROLITH, a custom 3D-printable shifter knob designed for the Thrustmaster® TH8S.

Combining a sculpted, ergonomic grip with a futuristic open-loop silhouette, AEROLITH brings together functional geometry, a premium appearance, and customizable multicolor printing in one distinctive design.

Features

• Ergonomic Grip — The sculpted body and generous open-loop design provide a distinctive grip shape for your shifting experience.
  

• Voronoi Anti-Slip Texture — Designed to enhance tactile feedback and help improve grip during shifting.
  

• Futuristic, Clean Design — Distinctive contours and carefully considered geometry give AEROLITH its signature look: minimal, purposeful, and unmistakably futuristic.
  

• Easy to Print: Designed with 3D printing in mind, featuring considered geometry and chamfered transitions.
  

• TH8S Compatible: Designed specifically for the Thrustmaster® TH8S shifter.
  

• Multicolor Design: The separate inlay allows contrasting colors or materials to create a personalized, two-tone finish.
  

• Chamfered Press-Fit Inlays — Bevelled edges help guide the inlays into its recess during assembly, creating a clean, integrated finish without visible fasteners.

Make it your own
Experiment with different filament colors and materials to create a finish that complements your cockpit.

Compatibility: Designed for the Thrustmaster® TH8S shifter. This is an independently designed accessory and is not an official Thrustmaster® product. Fit and press-fit tolerances may vary depending on printer calibration, material, and print settings.

Print settings

Please DO NOT scale the parts: This shifter knob has been designed for the THRUSTMASTER® adapter.

A 0.4mm nozzle with 0.2mm layer height works well with at least 15% Rectilinear infill pattern. Or use a Gyroid infill at 10% fill density. 

Supports are not required.

To avoid internal stringing, set to “Avoid crossing perimeters” and set the seam position to “Rear” for the knob.

Remove the part after the print sheet has cooled, then flex the sheet to release it.

Filament & Painting

Looks great when printed in black and white PLA.

Assembly

Simply press-fit the inlays into the shifter knob. You should hear a clean snap-fitted sound.

The thread and fitting dimensions are designed to match the official THRUSTMASTER® adapter. You can find the adapter in the files section of this project or download it directly from the official Thrustmaster Printables profile:
