Go to Boxes.py and scroll down until you see the Birdhouse/Feeder this is my project except it has tossed a sinker ball in the midst. So far I have cut the floor and all four side walls right from the pattern, the only exception is the roof panels. When I cut the first panel it came out 20 CM wide X 20 1/2 CM long also the cut out for the tabs on the gable were 13CM outside of slot to outside of slot, I need the slots to be 20cm so they will go together
I sure hope I have not confused the issue.
