Bristle Worm Trap for Reef Aquariums.
How to use it:
Place a small piece of uncooked shrimp inside of the trap, close it and leave in bottom of the the aquarium overnight. Collect it in the morning and dispose the worms.
Epoxy coated magnets or an old small glass cleaner, can be used to help move it to the bottom of the tank.
Alternatively, a piece of rock can be used to help it sink.
It can be positioned in any directions and the worms will find its way in.
Other sources of food can be used, like mysis or pellets, but they will attract less worms. Clams on a shell are also good baits and are less messy than chopping shrimps.
Happy hunting!

It will print easily with no supports.
PETG or ABS will make it last forever, but PLA is not a bad option either, as the trap won't be submerged in saltwater long term.
