So here is version 2 of my Leather Tools Rack. I needed some larger holes, so I decided to make larger holes on one side and a grip-load of small holes on the other.
Also, you will notice that the top row goes through the back of the rack. This is a design element not an error. I wanted to be able to put longer tools in the rack also.

There are a couple overhangs in the back that may require support, but that is up to you.
