Crumb Tray Alignment Tool

We have been trying to find a easy way to line up items in our laser cutter. Rather than making a Jig for every item, why not just make a quick tool that can be moved around on the crumb tray? I made these so you can make the corner and then use that to place your items on the crumb tray in the exact same place and get those great prints without having to align the prints every single time.
