Closing lid for the box with hinge

I had made a box with an hinge. This came out very good but it had a drawback. The lid was loose on the box. This would be difficult to transport. So I decided to make an additional locking mechanism. It is a kind of clam.  It is created in Blender using the original file for the box. This way I didn't had to do complicated measurements.

After 1:35 hour the printer was ready. But the distance on the inside was just a milimeter to big. It had no grip on the box. For the moment I solved that problem by putting a lot of layers of tape on the inside. You can see that in the third image.

This way it fitted good and stayed in place.

On the middle image above you can see how it stays locked around the box.
