Robust corner brace for simple frame

Made doors for my covered/raised garden bed. They were flimsy and the corner braces i made from wood cracked. I printed a design hoping for much improved rigidity and it worked!

Wood used was "1x2" which is commonly actually .75x1.5.

As this is outdoor, i printed them in ABS with an .6 nozzle at .4 layer height. They really want to pull off the bed even in a closed insulated chamber. Might round the corners if someone asks as this should reduce that tendency.
