I have designed a speaker holder that connects Logitech Z407 speakers to Nema 100 holes. The speakers are simply attached to the holder. Finally, I used double-sided adhesive tape to ensure that the speakers are parallel to the monitor. The entire arm can be 3D printed on a 3D printing platform with dimensions of 235x235 mm, suitable for printers like the Ender 3 or K1.
