Mason Bee House Remix

This is a remix of wcatherall's Mason Bee house. https://www.thingiverse.com/thing:3457603

I had an existing wooden bee house with cardboard tubes but a bird knocked out all the tubes (I guess trying to make a nest in there?). I found wcatherall's design and that guy knows his bees. Unfortunately, it wouldn't fit in my wooden housing.
I redrew his design from scratch in Solidworks so it would fit my housing.
One other change was to the holes for the screws on the cap. I had flat head screws handy, so my holes have a countersink on them.

Note that the front face is not flat, so put it on the back (with the screw holes) for printing without supports. The uneven front face is intentional, for two-color printing by changing the filament.
