Glyph Markers
thingiverse
A collection of roughly 1-inch arcane circle markers I use with maps or 3D terrain in my Dungeons and Dragons campaign represents spells like Glyph of Warding or other magical effects as desired. For something a bit larger, check out the two-inch wide Arcane Circle at http://www.thingiverse.com/thing:2005828.
