Organic Shelf Corner Bracket

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
