Coral Frag Rack

thingiverse

This is a magnetically mounted frag plug rack for marine aquariums. It was printed in PLA, but I suggest ABS or PETG for the longest life. Uses 32mm x 2mm rare earth magnets, available from numerous online sources. Mine came from Amazon. The magnets were coated in aquarium silicone, then glued in their holders. After several days to dry they were coated with multiple coats of black spray-on plasti-dip. For my next build, I'll use the solid plasti-dip and simply dip in the magnets. I'm hoping that will seal them enough to last, but no promises. Note: Fits most plugs, but not the 1/2" ones. Holes are 10mm, which is a good fit for most of the plugs I have found.
