Dog PlayPen Corner Bracket

I made these little brackets to keep the playpen 'square' rather than going all Rhomboid on me. lol. Super annoying Pretty simple design and print. No supports needed. Just stand on end and print 4 of them. I suppose you really only need 2 on adjacent corners. They resist flexing enough. 2 right angles will prevent the others. But I went with all 4 for symmetry ;-)
