A Simple Secret Box

myminifactory

UPDATE: I've uploaded "Box Short.stl" and "Lid Short.stl", which represent 62.5% of the original box's height for those who don't need the full size. These components also feature a slight design enhancement in the hidden corners, making it easier to keep the box closed. Both parts printed flawlessly after testing. I've seen similar designs before, but the latest one I found was made from wood a few years ago. This 3D printed version is surprisingly simple yet very effective as a "secret" box. Even with close inspection, it appears impossible to open the box without gripping the correct opposite corners on the right end and pulling them. Designed using Sketchup Make 2015 and printed in PLA on a Makerbot Replicator 2 with Makerware 2.3.3.42 "Standard" Settings (.2mm layer height, 2 shells, 10% infill).
