Ventilated Knob for THRUSTMASTER TH8S Shifter

An ergonomic, ventilated knob for the THRUSTMASTER® TH8S shifter. Ergonomic: The body is shaped to sit in your palm, with a rest on each side for your thumb and fingers. Ventilated: 30% of the shell’s indentations are holes that lead into a air chamber inside the shell. An inner core with six ribs keeps the shell stiff. Multicolor / multimaterial: The knob is made of separate parts, so any single-material printer can produce a multicolor / multimaterial result. Easy assembly: The crystal slides onto the shell, and the logo presses in to hold it there. No screws, no glue. Orientation lock: The collar keeps the knob from rotating on the adapter and covers the adapter's flange Please don't scale the parts: the thread and the fits are sized for the THRUSTMASTER® adapter. Have fun! Elements - Logo: Sits recessed in the crystal, its stem locking the crystal to the shell.

- Crystal: Faceted top of the knob, slides onto two keys on the shell.

- Shell: Main body with adapter thread, ventilation holes, grip indentations, side rests and keys.

- Collar: Lock nut with three grooves that fixes the knob's direction and hides the flange.
