The body is hollow with about 5mm thick walls, so you can put it on top of a Christmas tree if you wish. No supports needed, the body/head and wings print separately and notch into each other. They can be fixed in place with glue.

Update: I attempted to actually print this recently, and discovered that the slicing of the body/head got very messed up. The body/head has been fixed and re-uploaded, so print away!

Print the body/head and wings separately.

Fit the wings into the notch on the body and glue.
