New Clam for box with hinge

Today  I made a new clam for the box. I work in Blender. The file gave some trouble because during extrude. There were create a couple of loose vertices.  I had to repair the file so it could be printed without problems..     It took 1:48 hour to print the item.

The upperpart is a little thicker.  Now it fits around the box without extra tape.

It is a very simplistic way to close a box.....but it looks cool...
