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.

Thank you for your honesty! They measure about 1.96mm thickness, which is super close to 2mm! And thanks for the vinyl touch in the packaging:) Will buy again later (probably in bulk). I suffered from very bad tolerances on other listings, they were much thinner than listed, but this is actually accurate and honest. Glad I found it! 🥳

I bought these after reading the reviews since I needed some 6x2mm magnets for a few 3D printed projects. They are very strong little buggers. I liked the tip I had read somewhere about sliding them from the top one off of the others, that seems to help a lot. They seem to be working pretty well. I have ordered more and also various sizes for future projects.

Perfect for repairing a cabinet door where the magnets fell out. But now what do I do with the other 398 pieces?!

Magnets work great! Strong magnetic strength yet easy to pull them apart when needed. Unfortunately the storage box they came in arrived broken. The divider was snapped off inside, and the box itself doesn’t close. Not ideal when trying to store tiny magnets in a house with two curious kitties.

I use these 6x3mm as embedded magnets for 3d prints. They are quite strong. The size is slightly off by 0.1mm across batches, but for the same batch they are consistently sized.

Great size, great quality, great to cuddle with or use as a pillow. If you Are thinking of buying for sure do!!

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.
