"NINE" HANGING HOOK

There's not much to say here.   It's small, about 25mm long overall, super easy and fast to print, and useful if you want a lightweight hook that won't rattle.

The model shown is hanging from one of @TrocheHole's Oval Carabiners which did the job splendidly, but in the end I chose to remix another of his(?) models for my SIX HOOK.

Since there are no moving parts, print in any material, and it will probably scale up quite well if you want it bigger (but I haven't tried)
