These are button caps that can be popped onto the buttons on the Thrustmaster Sparco rally wheel R 383 mod.
For some reason Thrustmaster puts these buttons in a totally random order and I got tired of trying to search for the right buttons in games like Dirt Rally.
They should be a press fit. There is no number 1 or 2 because those are the paddle shifters. There is also no 11 or 12 because those are the buttons on the wheel base. I also included a blank button so you can add your own symbols if you want.
These are best printed at 0.15 or 0.2mm resolution, I used supports but if your printer is good at bridging you might be able to get away without them.
The numbers are 0.4mm tall so look at which layer they start on and add an M600 to your gcode to change the filament color.
