Makita Shelf Bracket

Someone else made one of these, but I could never get it to work. But since I saw I really wanted one, so I made my own. I thought I had made it to fit my print bed, but it ended up a little too big. I needed it smaller anyway for the shelf I made it for so I just scaled it down. I printed with 50% infill to make it stronger so it would actually help support the shelf.
