Make this Cheap and Simple Dog Hole Jig!

I wanted an easy way to map out woodworking dog holes in my workbench and couldn't draw a grid because of a finished surface, so I decided to make a simple jig from plywood. I had a couple failures when trying to make a jig sandwich in the corner instead of only having a front-guide. I realized it would be easier with a single guide. This is similar to a rocker product except I didn't want to spend money on a one or two time use jig. I used the Milescraft handheld drill press attachment but an alternative would be a router pattern bit of some sort.
The size of the jig and spacing of each hole will of course vary depending on your workbench. Most people base the sizing off the max extension of their bench vise.

Here are dimensions of my jig:
top plate:
- 14" long
- 12" wide
- 5" front to center hole spacing
- 4" side and rear center hole spacing
- 3" spacing between holes
edge guide:
- 14" long
- 1" wide
