This 3D printed button features a white-lettered tire mounted on a classic 5-spoke wheel, atop a fluorescent orange base to match the famous Hot Wheels track pieces. The button and wheel are printed together with a mid-print filament change, and the tire (with its own mid-print filament change for the lettering) is installed as a tight press-fit assembly post-print processing.  If you look closely, you’ll see the tire even has tread!
