A box for DSO-TC3. I used original foam insert, I only added some to the top part, too (1cm thick to protect the top).
I have cables stored separately, but i guess that you can squeeze test cables inside, if desired - just put them at the top. In that case don't install top foam, only protect LCD with something to protect against cable scratches or use a plastic bag for cables.
The author remixed this model.
Resized dimensions to fit my device.
