I show a simple way to use a round rally-style rim on the Thrustmaster T818 with the quick-release adapter supplied with the base. The assembly combines a 3D-printed part and a rim without electronic controls. I tested this setup with substantial force feedback, using a separate shifter to change gears.
Preparing the adapter and rim
I use RamjetX’s model reproducing the screw fitting of the older Thrustmaster generation. It prints without supports. For this file, the designer recommends PLA at 100% infill; that is the basis of the assembly shown.
The rim attaches to this part with M5 bolts and nuts. The video also mentions metal versions and the possibility of having the part printed if you do not own a printer.
Adding the T818 fitting
I then place the T818’s new-generation adapter onto the rear part. It slots in without force, and the collar tightens the connection. I also add the supplied retaining screw. The appeal is reusing the adapter already included with the base; buying it separately was discussed at €35 in this 2024 video.
Recognition and testing
Once the wheel is installed, Thrustmaster’s software detects it. I can set the rotation angle and recentre the steering if needed.
During my test, the wheel remains firm in my hands and I notice no play in the assembly. One limitation remains: the T818 lighting animations do not work in this mode. This rim without buttons or paddles therefore suits an installation where gear changes and other controls are handled separately.
