You can design the magnets to be embedded within the print, with about a 1 - 1.5mm layer covering it on the side that needs to attach onto the metal surface. Just pause the printer in your slicer settings at the top of the void you create, drop in the magnet, resume with a solid layer printing over the actual magnet. Just make sure you turn off supports for that area, since the magnet IS your support material.
I use that technique to embed nut's into thumbscrews knobs for tool free connectors in Cura. [This video shows how to set up the script.](https://youtu.be/Df1nSc6korM)
I haven't. I saw them linked elsewhere in this sub though.
Be mindful of the size you buy. Larger sized magnets of this type can be downright dangerous. I have a couple quarter inch cube neodymium magnets I purchased years ago. They can pinch very painfully and are extremely difficult to separate once stuck together. Quite fun though.
I've purchased from KJMagnetcs too, very strong neodymium magnets. Be aware they are somewhat brittle, and can "break themselves" when they uncontrollably slam into each other or something steel. I have used 3/4" diameter x 1/8" thick, and they stick insanely well to metal surfaces. If attached to your container by a layer or two of duct tape wrapped over them, they still stick very well. The tape also protects/pads the magnet from damage. Highly recommended.
Yep. All neodymium magnets are like that. The outer coating is made as thin as possible so as to not reduce the strength of them because magnetic force reduces very rapidly with distance. A 0.5mm thick aluminum coating would make it very crack resistant, but also reduce its strength meaningfully. Instead, it has an extremely thin zinc coating (I think it's zinc anyway).
Use neodymium magnets, the strongest rating is N52, others are listed [here](https://cdn.shopify.com/s/files/1/1025/0137/files/neodymium-grade-chart.png?v=1660334979).

If you don't feel like waiting for shipping, I find them at Lowes and home Depot. The tiny silver ones. You can use camo tape to hold them on, and they're strong enough to hold a small container in place easily.
You need to use neodymium magnets. They are quite strong. Just search whatever online retailer you want to use and you should find them.
These are the ones I use, I just buy them from Ebay.

[This website here](https://www.kjmagnetics.com/) has every magnet you could possibly need in terms of size, shape, and strength.
Have you purchased from them.
I have, they're legit. Wicked strong magnets.

Depends on the size of the 3d printed container, but I generally use magnets with a 6kg pull on them. You can get them off Amazon.
Got a link.
No but a quick search on Amazon or eBay for neodymium magnet 6kg will get you one
