I figured if the googly eyes were a requirement, I could at least compliment them with a moustache. This one is cut perfectly to support the CR touch probe, and simply relies on gravity and a clever inner-chamfer to stay attached to the extruder.

Print with the outside facing down, no supports, show me some 'stache!

Please note: I have no idea if this works on any extruder other than the Creality Sprite Extruder Pro. It must have the stock part cooling fan in order to stay attached.
