One side of Case is Peeling Off Printer Bed

Im trying to print the rear of the case from:

Im using ABS. Temp is 230/110.

It seems that the side of the case where the powersupply is is sticking firmly to the bed. The other side is peeling off. It also doesnt seem to of adhered well.. Any ideas on what im doing wrong?
