One thing I've also found is how your print is designed will affect warping/separation. Hard corners tend to warp and separate more than rounded corners. If it is not necessary to have a hard 90' corner, then design in a rounded edge. Long edges or rounded corners have more material near them to help bond with other layers/bed, while hard points or corners have less material, and the more/less material also affects cooling. If a round corner isn't possible, then adding a single layer brim to be trimmed off later can help. Example: Adding a small circle of material at each corner.
Obviously other people's design's may not account for this, or your design is dependant upon a hard corner there, but avoid them whenever possible. I've also found (and most engineers will know this) that a hard corner transfers loads for less effectively than a rounded one, so consider this for interior corners too. Whenever I'm making servo sleds for racing boats, I round as many corners as I can. Through both stress simulators and real life experience I've found vastly improved performance this way.
