What does "didn't work" mean? Did it fail mid-print in some way, or did it complete but everything was fused, or ?? Either way, I would suggest a smaller layer height - probably .2 or .1. And printing slower always helps when precision is necessary. But if your printer isn't well calibrated, that still won't help. Have you tried printing any of the various calibration and testing widgets found on Thingiverse? They can more quickly help you identify what the issue might be.
