I must say, this is a nice little template. It's got crease guides, so I'm going to crease before I cut. My build isn't going to be precisely 1:24, because I let the print re-size. The scale at the top of the page that says it should print at 7.5 inches measures in at 7 and 5/16, for anyone compelled to do the math.
Pay attention to the asterisks when pre-creasing. When you see them, refer to the text instructions in the pdf so you don't crease something you shouldn't.
The roof components, especially piece 8, should have asterisks in a few places but don't. Read step 10 in the instructions before creasing these.
