2 x 4 Marking Gauge/Ruler
thingiverse
A precision gauge designed to rapidly identify locations on the ends of a 2 by 4 inch beam (actually 1.5 inches by 3.5 inches). Based on this: https://www.amazon.co.uk/Rakuda-2-4-Square-Ruler/dp/B001Y51VUI There's another version with an additional side that fully secures the gauge to the beam. Edit the SLDPRT as you wish, but be aware that the VarPattern features can take a while to render. You need to disable trailing zeros under Document Properties, quit, and restart SW so numbers render without decimal points.
