Printed on my Ender3 (bone stock)
Printed sloooow (intentionally) so it took 14 hours.
I do not have the exact scale but using the corrected obj file (in comments) I set the X to 150mm with uniform scaling turned on (Simplify3D)
She looks like she would be life size for a pixie ;)
For those whit the skills she needs some more mass in the wings to keep her from falling forward.
Her wings look perfect! But maybe about 10% bigger or a tiny bit thicker would keep her upright.
Supports (from bed only + added some for the wings (make sure you connect all of the wing ones so you don't loose a support tower like I did. Was able to tape it back up while it was printing.
