Print in place Modular Box Size Small

Here is a simple print in place box I made to help me organize my workbench. I created each box to be printed in one piece and stackable for easy organization. 

These are great for storing screws, washers, snacks, or anything small! 

There are two different models, one is printed on its back with no supports, and the other has supports built into the model (so no auto generated supports) and is meant to be printed at a 45 degree angle. The regular box looks a bit nicer and has tighter tolerances, however the one printed at 45 degrees has the best strength and the smoothest opening action.

The spacer ring is glued on top of each box and sits in the corresponding slot in the bottom of each box. The only exception to this is in the box printed at 45 degrees, this box has the ring built right into it. 

Please let me know if you have any suggestions on how I can make this model or system better! More models coming soon!
