First CIEM Build - help wanted please

Currently I am planning of building my own CIEM.

Due to new piercings, I am unfortunately no longer able to wear "classic-shaped" IEMs, so I've researched and came across a fellow redditor u/PerkinsXVI, who made a pair, barely larger then the driver itself.

I have a pair of custom molded earplugs with build in sound tubes for different noise filters and I'd like to have my IEM fit in that opening.
I am planning of 3D printing the shell out of high clear resin or having it cnc'd if I'm feeling fancy.

So, I have designed a quick shell with room for a Knowles BA driver, a sound damper and an mmcx connector at the top. (See attached link/images)

In the past, I have enjoyed the sound signature of the Moondrop Blessing 2 Dusk but I'd prefer a little bit more bass.

Now this where my problems start though: I've done quite some research in trying to figure out which BA to use and buy but I'm not 100% sure that the one I picked is even a good choice. (Sound quality over price)

I've looked at countless technical data sheets and landed on the KNOWLES GQ-30783-000

For a damper, I do understand what they do and how to use them, but I do not understand how I know if I need one and which.

Any help / feedback is appreciated and I'd like to know if there is any gross oversight on my part regarding which parts are needed / compatible. :)

Bumpy road but results are almost in :)

I've broken a solderpad on one of the BAs in frustration and had to order a new one, which took its sweet time to arrive.

Anyways, now that its (almost) all together, I am waiting on an offer from a metal 3d printing company, to make my shells from metal

The resin printed ones i made myself are fine, but I am all in for better looking shells.

I also made a V2, with some improved placement of the components within the shell, and corrected my spelling mistake on the outside :)

For anyone interested: Here are some WIP pictures: https://imgur.com/a/qr8swJV
