Advice needed for frag racks

[rlkilwil]

Hey all!

My hubby and I recently purchased a 3D printer and I am looking into printing out some magnetic frag racks for my tank and possibly for other hobbyists! My only issue is that I don’t know what kind of magnets to buy. I assume neodymium magnets because they’re very strong, but they are all rated at different levels of magnetism. Can someone help me understand this and pick out a magnet that will work?? Or even just suggest one, an amazon link would be amazing!

Thanks in advance!
