first i printed the Megaphone speaker, but i couldn't find the speaker in my home. so i ordered a new one. waited for 1 month. got the wrong ones when it finally shoved up. (52mm).
when the correct ones arrived 1 month later, it was not a tight fit and made a ratling noise when it played due to the loose speaker in the design.
so i started over with my 52mm in Fusion360.
This is for a Aiyima 4ohm 3wats 52mm speaker found on aliexpress.
Made the Horn, Bottom, Bracket/stand and the Lid stronger for the mp3-player. (broke the original a few times)
there should be no need for support material.
