Sorry to hear that, were you printing in PLA? ABS is best, and sometime the nozzle offsets for a 3D printer may not be the same as the ones that have worked. In this case, you may have to adjust them for the parts to stop sticking to each other. Can i get some details about your 3D printer? We might be able to help out.
