Dovetail ruler
thingiverse
This tool needs to be standard issue in every woodworking shop. While length might not be perfect, it should suffice. I developed three versions - 1:4, 1:6 and 1:8 - each with a hole in the corner for an even better fit. A wall holder has been added as well. Please let me know if you've found it useful.
