A lid for my Mac Pro trashcan. Let the hot air out, but protect it from coffee spills. I like the cubic shape. Tried a catenary, but it didn't really do the right thing.

This design is the same as the previous, but simpler in order to improve how it prints (I have leared a little since my previous design :) ).

Scale is 1 unit == 1 mm. The object is split into sections to hopefully make it possible to print on a smaller printer.

This thing includes the macpro 'shroud', but that is not part of the object.

I include the lid as one piece, and also split into thirds and sixths.
