Magnet Mount Feeding Ring, 80mm Corral
This ring walls off a patch of the water surface, so you can drop food inside it. The clear opening measures 80mm across. It is a wall around a patch of the surface. A pocket on the back holds a 12mm by 3mm disc magnet, and we fit it for you. The pocket is closed on every side, so the magnet sits inside the print and never touches the water, and it goes in part way through the print rather than being something you fill yourself. The matching disc for the dry side of the glass comes with it, coated, since that one sits out in the open. Set both discs on clean glass and line the outside one up with the one inside. We print in PETG. Aquarium keepers have used it submerged for years. Rinse before use.

Common questions
Which feeding ring size should I pick, 60mm, 80mm, or 100mm?
Match the size to how many fish feed at once. A bigger ring gives more fish room at the surface without crowding.
Should I pick the magnet mount or the rim clip mount?
Pick the magnet version to hold the ring against the glass at one set spot. Pick the rim clip version to straddle the tank wall instead.
Does the magnet come with the magnet mount version?
Yes. The magnet version ships with its magnets fitted. One 12mm by 3mm disc is sealed inside the pocket during the print, and a matching coated disc for the dry side of the glass comes in the box.
Does the thumb screw come with the rim clip version?
No. The rim clip straddles the tank wall and snugs down with a nylon thumb screw, but the thumb screw is not included.
