+# In one-at-a-time mode, only one extruder can be enabled to print. In order to maximize the number of objects we can

+#  +--------------------------------+
+#  |                                |
+#  |                                |

+#  |       X                X       |    y     - X's are the nozzles

+#  |                                |    |
+#  +--------------------------------+    +--> x
+#
+# In this case, the nozzles are symmetric, nozzle (1) is closer to the bottom left corner while (2) is closer to the
+# bottom right. If we use nozzle (1) to print, then we better off printing from the bottom left corner so the print
+# head will not collide into an object on its top-right side, which is a very large unused area. Following the same
+# logic, if we are printing with nozzle (2), then it's better to print from the bottom-right side.
+#
+# This iterator determines the print order following the rules above.
