Case or enclosure for Pi 3 and Cluster Hat and Pi Zeros



Has anyone found a way for protecting the Raspberry Pi 3 with the Pi Cluster Hat and Pi Zero’s in the Hat, either partially for the base Pi with a partial case, or with something like a fully enclosed project box (maybe with a fan to cool it all down) ?

Can’t see anything off the shelf apart from some opensource maker plans for custom laser cut acrylic which I can’t do?
