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

I bought these for use in my 3D Printing projects to remove the need for having to connect parts with 3d printed latches/hinges/etc. I was hoping to find square but found these instead and the price was right (I think under $10). Now I cannot stop thinking about magnets. I've made several designs using them, ended up needing a few of them for items that I lost the magnets for while building, and also just have fun in general using them like little fidget toys. I ended up buying another pack of just the 6mm because those are pretty strong. Definitely going to be getting more.They work well when directly connected. All the things I used them in hold well and can usually find each other pretty quickly as long as there isn't too much in between them. Using the 4mm magnets, I've been able to get sometimes 4mm distance between them. This is while making a hole in my 3D Prints to be able to push them in, so about 2mm on each part connecting. Even when them enclosed in a pocket, they still hold well, but the 6mm seems to hold the best. Your best bet is to keep stacking them if you need more strength out of them or to go to bigger magnets if you aren't able to get the hold strength you need after about 4 or 5.

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.

Perfect little crafting magnets. 2 sizes. Super tiny and Super super tiny. Smaller than I thought they’d be, but I don’t mind. Great price too. And they work great on my ceramic pieces to create fridge magnets.

I build small wooden keepsakes. These small but strong magnets were what I needed for one special gift - a close able case for a coin set with the birthday guy’s birth year. These are strong enough to work together when the box needed to be closed and opened just fine. Had to buy a bunch, but that gives me opportunities and ideas.

Super strong. Love the case it comes in for storage too. Magnets all come together but they are easy to separate and work as expected

Perfect little craft magnets.

Exactly what I needed.

The magnets worked how I wanted but the strength was just not there. Weak magnets good for small crafts or maybe hanging up paper. Not good for strong holding
