FlashForge Creator Pro ? Design or Print Issue?

Hey guys,

Having the following troubles with a design I'm trying to print. I'm not sure if the slope is too extreme for printing or if I can tweak settings to get a cleaner print. I've tried what feels like everything under the sun (adjusting extrusion temp, bed temp, print speed, using ABS slurry, etc, etc.). I don't want to print lying down because of all the supports I would need that screw up surfaces.

Material: ABS (Black Hatchbox)
Extruder Temp: 220C
Platform: 95C
Layer height: 0.10mm
Print speed: 40mm/s
Retraction length: 1.3mm @ 30mm/s
Shell count: 4 w/ 30% path overlap
Top solid/bottom layers: 8
Infill: 15% Hexagonal
Extrusion Ratio: 105%
No supports, raft, or cooling. Top and door closed.

The bottom curved edges of my design are printing so sloppy and the bottom always seems curl up a bit even with ABS slurry. I've tried printing with both FlashPrint and Simplify3D with little luck. I was able to solve the ringing/mimic by removing the left stepper motor, but my main concern right now is the bottom corners.
