This is a set of bases for various miniature games. I've included as many sizes as I could think of for the most common units. 

All the bases have space for 6X2mm magnets. Included is a “magnet tool” that helps with polarity. You just add magnets  to the tool in the polarity you want then place the base face down on top. It's not an essential tool but I got fed up with covering my fingers in superglue when magnetising my bases. 

If you want to create custom sized bases with these, I have included the Fusion360 file with parameters set. It's my first time using parameters so it may not be the most efficient use of them, but they are there if you need them.
