I felt itchy the entire time modeling this. Its as accurate as I could make it, but some of the cute whiskers on this little flea would just be too hard to print up. So perhaps you could leave the little spiderwebs on the legs or something.
And as a side note I plan to make the rest of the ringmaster accessories soon, just fine tuning what I do have already (top hat and megaphone) and will be adding the whip and hoop later.
The model shown is made of PLA plastic high setting on the Relpicator2, and about 4.25 inches tall (113 mm).
You should use supports.
