So I am trying to magnetize the bottom of my Ogors and I am finding that the 5mm x 2mm magnets I got (per a suggestion from a video I watched) do NOT sit flush with the bottom of the bases for my Leadbelchers. Which in turn means the magnets have no pull.

I then decided to see what would happen if I stack 2 of the magnets, and thats too high, causing the base to rock slightly. But it DOES stick the mini down to the plates in my custom case.

So what magnet size should I be looking for? would like 6mm x 3mm work for the basic stuff? What size should I grab for say an Ironblaster, or a Mournfang?

Or should I just buy some green stuff and use that to basically fill in the gap between the magnet and base and force what I got to sit flush?
