Meshed two brackets together for a corner. Sliced in Ult Cura 4.11.0 with supports(85deg)

update 17/9/21: added a 1g brace for the large open area. +Printed braces with 15% infill. -reason: printing the corner piece w/ supports gave me fragile sections. -positives: meant to use glue but they snapped in place near perfectly, must be beginners luck. -negatives: are 5-10mm short, covers my breaks but not the entire fragile sections. -misc: started to learn tinkercad and 3d builder.

Thanks
