The Blacksmith roof was definitely one of the most difficult to print and definitely to assemble. These pieces also are the most changed so understand that your printing experience will be slightly different than mine since I was actively printing these building while it was in its early beta stages.
When printing the model I tried as much as possible to not have to support the roof shingles while providing a smooth gradient of elevation. This inevitably made the undersides of the roof a bit more messy due to the curvature of the roof but the exterior appearance looks fantastic.
Special Note of Version:
As of March 26, 2021: Major changes have been made to the roof files of the Blacksmith building. My roof files will not match anything downloaded after this date. However final appearance will match it is mostly assembly that is impacted.

Required Print Processes
The most notable difficulty is that ALL pieces of this set require rotation of opened STL file to be flat on the print bed when loading into your slicer. The largest thing to look out for is to make sure that the bottom of each base piece is flush against the build plate. This ensures a good solid layer of adhesion for your print and best success while printing. When looking for the side to put against the build plate look for the side that has no details. In the case of BW Wall B I did lower the wall slightly into the build plate to ensure a solid 1st layer for printing as well.
Image below shows rotation of piece from Fishers Hut print logs but concept is same for Blacksmith as well.
