Hidden Mickey Breeze Block

This is my version of the breeze blocks recently added to the new Downtown Disney remodel at the Disneyland Resort in California. Four of these breeze blocks together create a Hidden Mickey. The screenshot is just an example with the Hidden Mickey highlighted orange. I have included an STL that will fit in the "ear" portion, as well as an STL that will fit in each quarter of the "head" part of the Hidden Mickey, if you want to do an assembly.
