This amplifier is mainly created for cell phones that has their speakers pointing downwards.
It is made so you can charge the phone while using it. There are slots for the charging cable both in the front and the back.

I printed it without a raft and no brim.
Some suports is needed but not much.

I printed it in Flashforge green PLA

It works great with my Samsung Galaxy S20 Plus, and with my nephews iPhone.
