EDIT: After making new pictures I have realized, that this gable is in two parts, so I guess you have two split my model. I'm sorry I have no clue. Maybe I will look into it at a later time
I printed everything in PLA and with a scale of 120%.
Because of a gap between the roof parts (scaling error?), I designed (;-)) a gable.
Used a plastic glue to fixate it.
It's outside for two years ('25) now. No problems
The author remixed this model.
