Small Box with Hinged Lid
This is a small box (55mm x 55mm x 30mm) for storing....whatever. I am using to store fasteners that come from McMaster-Carr in a bag. Much easier to organize and identify.
The lid snaps onto the box and stays where you put it.
You can print it with fairly low infill, but don't go too hollow on the lid so it doesn't break when snapping it on or off the box.
