Battletech HexBase solid w/ Magnets

I filled in the underside of the base for two reasons:
1.I've found with other bases that the thickness helps with resistance to heat warping
2.The counter bore helps the magnets stay attached

The openings are sized for 3/16"x 1/16" magnets. I find that one is enough for plastic models, and you'd probably want two for metal ones, but that's untested.
