Gridfinity Bolt Tray

I wanted a bolt or tool tray that I could use while working on my car, but could also place in my Gridfinity system that I have organized my toolbox with. It is a nice way to keep your bolts together, especially if you're the kind of person to just toss bolts on a windshield cowl or in a pile like me. 

When printing: 0.4mm Nozzle, and be sure to enable the “Detect thin walls” feature in your slicer so that the metric rule is printed. If you do not do this, it will not print the measurment markings.
