The key search words in your (Chinese? better than rewarding Amazon with even more extra fees) store of choice I wound suggest:

3.5" to 5.25" Internal Hard Disk Mount Rubber

But don’t get the ones where the inner mount (of the 3.5" drive) is the same piece or bolted/screwed into the outer mount (5.25").

The ones in my pic have fairy big rubber nips in between (each secured on both sides), 4 at the bottom (that support the weight if the disk too), and two on the sides.

Also such 5" brackets you mount anywhere rally, even on the outside of the case, lol.
In one case without the 5.25" bays (at my parents, quick job) I mounted two disks on such mounts on that metal mesh between the PSU compartment and main compartment.

Prosecute like one of those fancy French girls?
(Marie Antoinette for example)

… is it possible that these uneducated plebeians just put “fetish” in the search?

Yeah, idk what tf those age brackets are, it’s like they haven’t updated them since they first set up the graphics for the statistics.

If a step-coworker gets stuck it better not be physically or it’s NSFW. If it isn’t physical, they just get fired bcs their ass isn’t doing the job.

Yeah, it’s fine … wait, IronWolves in a living space? Paired with that acoustic desk it must be like a train yard, but with more vibrations :D.

Edit: wrote this before I saw your comment acknowledging the same.
Well, with HDD there is the noise of the drive itself (the constant one & the searches, spin-ups), and the vibrations which can get acoustically amplified. For the former you need a case, any case, maybe a case in a case (ventilated ofc), for the latter I’ve always (since late 90s) had my HDD on full rubber, no non-rubber connection to the case.

My current NASies all use these (in desktop cases, I don’t like server hardware if it isn’t necessary, like with disks):

(They cost like 2 monies with shipping.)

So if going the 3D-print way, as you mentioned, I would def add the suggestion of incorporating thicc rubber pads or rubber straps into your design, like these ones (I’ve used them a lot decades ago, the only commercial option for silent PC enthusiasts at the time, but I’ve built then myself too):

(It’s rigid, the disks won’t fall out.)

I bet that fish can inflate!

New gens are ruining everything - “vertical video” gen-z, really?
Y’all need a spanking.

Which genre is that??

Yes, exactly this.

But they also then spray the gaps with reflective material (aluminum-based shit maybe?) and seal it with a thicc cover material for protection.

Did he have his ribs removed (which he also ate)?

… like, as a punishment, and you volunteer?
