I am a teacher and created this box to keep passes in. It is a little wider than a letter size piece of paper since our passes are simply letter sized paper cut into thirds. It has holes, stand upgright, and has a space for a name. I imprinted my last name. I created this with Blender 2.69 running on Linux. Printing with supports on a Makerbot Replicator 2 at low resolution takes about 6 hours.
