4, 6 and 8-inch rulers
thingiverse
3 lengths of rulers/spacers that I made to help locating deployment points in Warcry, but might be handy for designating zones etc. in any game. The measurement is taken from the outer edge to the center of the little hole. If you want some 3" deployment zone markers, check my other uploads. I might make an extension bit or two, but these are fully usable as they are.
