How to Magnetize Resin & Plastic Bases For Miniatures


Here is a great tutorial on how to magnetize resin and plastic bases for miniatures with all the sizes you’ll need, and tips to make it easy!

Rob has magnetized basically every miniature he owns and has been doing it for years. So if you’ve been looking to get your miniatures bases magnetized, this will cover all the tips and tricks, along with all the sizes of magnets you need and where to get them. That way you can get your army magnetized in no time! 

There are some major differences between magnetizing your resin bases and your plastic bases, so we’ll show you how to do both. Let’s get into it!

The video above focuses more on storing your minis, but it has some good tips and we’ll show what you need for the base magnetization. Also, if you want to store your minis for cheap, the video is a must-watch! Or, you can see more about how to do it here.

Steel Sheets & Storage

You can grab these sheets here, and they are really easy to get different sizes of, or you can always just cut them with some metal clippers if you need special sizes.

They are fairly affordable and Rob just puts his down in the case with 1″ double-sided foam tape, and Duct Tape around the edges…

How To Magnetize Resin Bases

magnetize plastic and resin miniature bases 3There are two main options here. First, Squad Marks has tons of pre-cut magnets that work great for resin bases. They have them all the way up to 50mm, but generally, you don’t need too much over that size.

So for the bigger minis, you’ll have to cut your own, but we’ll cover that in a second. All you have to do with the Squad Marks sizes is peel and stick them on your minis’ bases, it’s really that simple! So if you just grab a steel sheet from above and the Squad Marks’ magnets, you can literally be done in minutes.

You can see above, they fit really well and are actually a hair smaller than the bases, which is what you want.

That way you don’t have to come back and trim anything later, they are also strong enough that they don’t have to cover the whole base. To do this, simply put your base down, trace around it and make sure to cut the line so it’s not hanging over. As you can see in the pic above, how it’s not all the way to the edge.

Just to note, talking about the base sizes, there are tiny differences in companies’ resin bases, so be sure to measure out and not just assume it will be the exact perfect size. It’s often the tiniest tolerance, but it can make a huge difference.

How to Magnetize Plastic Bases

magnetize plastic and resin miniature bases 7Plastic bases have a little gap between the ground and the center “roof” of the bases, like the one above. So, all you have to do is take a magnet and glue it in that open spot. Rob recommends using the Magnet Baron ones because he’s never had any problem with them. It’s really simple, you just glue it in and you’re ready to go. The main thing you need to watch out for is which size magnets you’re using.

Here’s a quick reference sheet to go on with the diameter measurement listed first.

  • 1/4 x 1/16 for lower 25-27mm. 
  • 3/8 x 116 for 32-50mm bases (2 for 60mm) and then more as needed.
  • 1/2 x 1/16 for the really big bases like 130mm.

And maybe more importantly, if you use a magnet that is bigger, you can actually have too much magnetization and damage your minis when pulling them out (or that snap to each other).

But, if you stick with the sizes above you should be good to go, just remember, if it’s not holding for bigger minis, you can just always add more magnets to the base.
