+# Angle Bracket System
+
+
+
+
+Please see [entry.scad](./entry.scad) for config and building. Make sure the correct rack profile is configured in [rackFrame.scad](../../../config/rackFrame.scad).
+
+This uses the [angle brackets](../../angle-bracket/entry.scad) for the sides, but creates a full honeycomb tray spanning boxWidth and boxDepth for more stability, ventilation and less print material.
