Assembly Instructions:
Print both main parts: the acoustic chamber and the phone stand.
Ensure all surfaces are cleaned from support material.
Insert the acoustic cylinder into its designated base slot.
Align the phone stand securely on top of the base structure.
Place your phone in the holder with the speaker aligned toward the acoustic chamber opening.

For best performance, ensure the phone speaker is fully aligned with the sound channel opening.
Light sanding of contact surfaces can improve fit and stability if needed.
