Reef Aquarium Bristle Worm Trap

This is a trap to catch bristle worms in Reef/Marine Aquariums. It is designed for a standard frozen food cube to be placed into the middle section and the trap placed on the bottom of the aquarium. I have printed in both PETG and PLA. I have read that long term PLA will break down in a saltwater aquarium. I haven't found this to be true, but I haven't left these in the water for more than 48 hours at a time though.
