Hatch cover for Cas

I just printed Cas: https://www.thingiverse.com/thing:2854288 , the complete version Cas.stl, but scaled down 70% (therefore the somewhat rough appearence).
I do not intend transporting any cubes. And in my opinion, it is too dangerous sailing the high seas with an open hatch.
So I made her this simple hatch cover.

I am a great fan of these cute little boats ! ! !
