Unfortunately, 3mm is too thick for the Ellison, and 2mm is too thin for InterSpace hex tiles. So you will need to cut 216 hexes (42 cuts of 6 hexes each) from 2mm foam and glue hexes together in pairs to produce 108 4mm hex bases.

InterSpace hex tiles TM demand that you manufacture them from the highest quality materials. Do not attempt to use inferior materials or processes.
