I have combined three ideas together:
Noise is directed to the back of the printer - I measured noise reduction about 6 db!
Basic version has length 10 cm, extended version 12 cm. Added version without text and with higher (plus 2mm) profile for smaller reduction in air flow.
I just used black marker to highlight the text.
Infill: 15%, Support: No, Enable Bridge Settings: Yes (Cura - Experimental)
