RHINOCATS 400Pcs Small Magnets, 4 Different Sizes Tiny Mini Magents, Multi-Use for Fridge, DIY, Office, Hobbies, Crafts and Science

These RHINOCATS 400Pcs Tiny Magnets have been working perfectly in my 3D prints. The variety of sizes is super handy, especially when you are working on different models or parts that need different levels of hold. Despite their small size, these magnets pack a strong grip and stay firmly in place once installed.I’ve used them for everything from lids and enclosures to tool holders, and they’ve never let me down. The quality feels solid, and I haven't had any issues with chipping or demagnetizing. Great value for the amount you get, too.If you're doing any kind of 3D printing that involves modular parts or closures, I highly recommend these.

I purchased thes to install on my N-scale steam locomotives. I run a lot of older 4-4-0, 2-6-4, 0-6-0 steam engines on my layout. The assoted sizes alow for finding the right strength and size to glue to my undercarraige of the loco. Of course they wont work without having something to attract to so I also install a thin 0.025 piano wire in the center of my track. This is installed in areas that have a grade or where there is difficulty with traction in pulling a realistic number of passenger, freight, or ore cars for the given engine. Not many of these steam engines can do much without some means to increase traction. The magnets are unseen and provide a downward force on the traction wheels which indeed helps the pulling power and effectivness of the locomotives. My track was already layed but if you are installing new you may find it resonable to install strips of light steel sheet that can be cut with shears and placed under your track to provide for the attaction. This system will work for most any scale just size accordingly to the size needed. By the way Amazon also proovides the small piano wire in differnt lengths. I used 36-inch.

Stromg and well packaged. Good quality metal, strong magnets for the price. Won't be disappointed.

Use them in 3d printing and they function well for that. They appear to be dimensionally accurate, though I didn't check all of them, just enough to double check. Packaging leaves something to be desired, mine showed up in a metal box with foam leaving a big ball of magnets to go through. They stick together and stick to metal, so they work, not the strongest but they are small so, not really anything against them.

Great for Warhammer models, and are very strong. Work well with tabletop stronghold magnetic cases.

Not super powerful but they do the intended job; attaching limbs to miniatures. Good value for the price.

Magnets are nicely packages and have foam padding to keep from sticking to the metal container. Magnet sizes as described. Good value, especially for the amount and variety you receive.

I bought these to use with some cosplay items to change plates on an item I 3D printed but they are just not strong enough for that. Based on them supposed to be for "crafts" and "mechanical" I needed them to be much stronger than they are. They are far too weak for what I needed them for. They aren't really bad, but for cosplay and other things that need a strong hold, these just don't cut the mustard.
