Jiadian Electronics USB3.0 Four-Port Splitter Enclosure

The store said there was no matching casing, so I designed one myself. It requires four M2x8 flat-head or round-head screws.

You can just poke them open directly with a screwdriver   25.11.9 Update: I redrew it, and now all hole positions are correct
