After printing the hexibase micro t-line speakers I noticed echoing when listening to spoken content. Covering the port stops the echo sound but also makes the speaker sound worse.

This muffler seems to improve the echo without totally losing the sound from the port. 

I printed this with two perimeters and no solid layers top or bottom.

Infill was a matter of some experimentation. I ended up using a height range modifier to print the part with mostly 25% gyroid infill but with a section of 40% gyroid in the middle 3mm, definitely experiment and comment your preferences if you make these.
