Lup Earplug - Reduce noise

So, I lose 1 of my loop earplugs so I printed a new one based on the original:

It is not as comfortable or smooth as the original (depending on your printer, filament, etc. ), but it works, reduces noise and lets you listen. The 3d model has a wall that does not allow the sound to enter directly into the ear, but makes it go all the way around the earplug.

I understand that basically, the logic is that it works similar to the human ear, and reduces the decibels that enter the ear canal.

I am not a doctor or anything similar (luckily), I just lost one of my earplugs and replicated it, it works like the original, without the mesh and the filter where the tip would go.

To this, you only have to add the silicone tips of any in-ear headset.
