Oui oui, I have croissants in my Christmas tree! 

This is one of my first designs I made in Fusion a couple of years ago. And every year people say how cool they think the croissant ornaments are in my Christmas tree 🥐🎄

Size (approximately)
In mm: 107 mm (height), 60 mm (width), 30 mm (depth)
In inches: 4.2 inch (height), 2.3 inch (width), 1.2 inch (depth)

Of course you can scale the croissant to the size you would like. 
I've printed them with ESun ESilk PLA Gold, no supports needed.
