USB, SD Card, and audio cable extension mounts

I recently mounted a mini-MAC under my workbench and I had to crawl under to get to the USB, mic/headphone, and SD card slots. That would not do, so ordered some extension cables and drew up a couple of jack mounts to be installed under the bench top. They fit great the very first time and are mounted with ¾ X #6 wood screws with a countersunk head (I used two 1” X #6 screws for the holes in the middle of the USB/audio mount). Make sure to pre-drill any holes and put a little wax on the screw
