To print it standing on it's flat base, rotate in X axis:

E1 90
E2 72.848535
E3 62.001095
E4 51.153629
E5 40.306158
E6 29.458701
E7 17.307846

S1 90
S2 109.119673
S3 119.967181
S4 130.81468
S5 141.662012
S6 152.509647
S7 163.356985

This way you can print it without support.

Also, Slic3r wasn't able to slice it correctly thanks to bad geometry.

I rotated it and repaired it. Files are ready for you Opossums. Just tell me where to sent them.
