Coroplast Edge Bracket

I was building an enclosure for my Ortur LaserMaster laser engraver and needed a set of brackets to hold the coroplast together. There were some on Thingiverse, but some were too thin, some didn't fit well, etc, so I made yet another version.
These are pretty beefy and hold well.
Look in my designs to find the corner bracket too, to join the sheets at the top and bottom corners. [https://www.thingiverse.com/thing:5323778]
