HP Dial for 45 mm Miniatures - Columns

I've been really enjoying Cthulhu: Death May Die, but a whole bunch of the monsters are on 45mm bases! So, I went ahead and put together this version of my HP dial so that they'd fit nicely on top of it =)

I used a rotary tool to grind off the little plastic nubs from the bottoms of the model (where they attach to the bases), then glued one of my little steel discs to the bottom of each one. This allows them to magnetically attach to the HP dial, which makes them nice and easy to move aroun
