I'm trying to print a 2-part case in ABS that i can screw together but every time I attempt to print it, it begins to warp on the corners I've added a large brim (10 outlines, 2 layers) and it still lifts. I've used hair spray to help adhesion but its still not enough.

Does anyone have any advice that way i can get a case that actually fits together correctly? I have Cura and Simplify3D and im working on Lulzbot Mini.
