Water proof magnet

[Sitthanon]

I was thinking of 3d print a frag rack and was wondering what I could use to make my magnets water proof before i print them into my prints. Want to be extra safe incase the print isnt tight

Was thinking of dd putty, would that work?

I found some waterproof magnets on Amazon that I was planning on using for the same purpose

I hit the watch button, but got stuck on the same issue: (Seahorse feeder) and wanted the OP to know this is a GOOD question!
Hey while we are at it, does the OP or anyone have a clue on strength per glass thickness? I got 2 big tanks with thick glass (219 & 150g)

use the waterproof magnets mentioned above as well as incase it in hot glue as part of your design
