I've downloaded the instructions from your drop box.
This is absolutely gorgeous.
I'm in the middle of my build for next year but I'll have a real good look at building it some time after Jan 2025 for 2026 Brickvention in Melbourne Aus.
After having a good look at the io file I can't see any reason why this can't be tweaked slightly to make it work perfectly.
Thanks for sharing this wonderful design.
