This design should print nicely on a Printrbot Metal Simple with no raft or support. Should spin right off the print bed with minimal work. If the rings are fused, try adjusting the filament diameter. I usually start by adding 0.1mm to the measured diameter of the filament I am using. If the filament measure 1.68mm using digital calipers, I will tell me slicing software that the filament diameter is 1.78mm.
