A box with a lid for Arduino / Elegoo Uno R3. To Prevent a lid self-unliding, a stopper (zatyczka) and peace of wire are used -- no any screws or clamps etc needed.

The arduino and a lid sit in the box very tightly, with offset +-0.1mm.

Also there is a solid lid in case someone needs to make holes for contacts manually.
