Coral Frag Rack (BYO magnets)

thingiverse

Coral frag rack and magnet holder. Holds up to 21 frags, you can superglue your magnets in after printing. The holder actually works better if you use it with the printed side facing the aquarium (magnets closest to you). The holes in the middle row are a bit larger than the front and back rows, so you can either have your frag plugs fit tight or fit loosely. (made for 3/4" frag plugs). Print in ABS for best maintainability in a reef aquarium. I got the Black Rubber Coated neodymium disc magnets (1" diameter x 1/2" thick) with protective rubber coating from K&J Magnetics. (DX08BR-N52). These are SUPER strong, so you might want to go a bit weaker if your aquarium is thinner than 1/2" glass. If you don't print at 100% infill it can absorb and ultimately get water-logged, which will make it heavier.
