ASA-Pro Failing?

Hey everyone, I have these little clips I have been trying to produce with some amount of flex but considerable strength. I've tried a variety of materials such as ABS, ULTRAT, PETG, and now ASA Pro. 

I just got a new roll of ASA Pro this week and opened it a few hours ago to do some test prints. I tried printing two of these models but one tab kept failing for some reason. I’m assuming that I won’t be able to print this the way I want it. I was trying to print at an angle to add strength to the little tabs and the rest of the piece as well. I’ve done this with ULTRAT and PETG with better results. Any tips? 

P.S. Finish quality isn’t as great as I thought it would be either. I’m printing with the Zortrax side covers.
