Coral Frag Rack (BYO magnets)

thingiverse

Coral Frag Rack And Magnet Holder. This innovative design holds up to twenty-one frag plugs securely in place. Simply superglue your magnets into the holder after printing for a rock-solid hold. The rack performs optimally when used with the printed side facing the aquarium, with magnets positioned closest to you. The mid-row holes are slightly larger than those on the front and back rows, allowing you to choose between snug or loose frag plug fit. This design accommodates three-quarter inch frag plugs effectively. For optimal durability in a reef aquarium environment, print using ABS material. When selecting magnets, consider purchasing Black Rubber Coated neodymium disc magnets from K&J Magnetics (DX08BR-N52). These high-strength magnets feature protective rubber coating and measure one inch in diameter by half an inch thick. However, if your aquarium has thinner glass than a half inch, you may want to opt for slightly weaker magnets. To ensure the rack's maintainability, it is crucial not to print at less than one hundred percent infill density. This can cause water absorption over time, ultimately leading to weight gain due to water-logging.
