Works for spinning reels and some fly reels. I've got a 1000 to a 6000 size reel, as well as a fly reel mounted on it.

Mount the hanger under a shelf or something, then hang the reel on it.

Works well with M3 screws.

Settings:
Infill 15%
no support
Screw holes print best at 0.2mm layer height. Works for 0.32mm too but it's sloppier.
