About this 3D model

This is a redesign of a model that I found here. I thickened up the walls because they were so thin that they cracked and broke as I attempted to check it for fit. Also I tried to improve the airflow. I printed it with a brim because it's tall and I didn't want it to fall over. Also I didn't print with supports because I didn't want to break it while I was cleaning it up and my machine is good with bridging.
